critique-composition

Critique spatial balance, whitespace, rhythm, and gestalt grouping in screen layouts.

What is critique-composition?

Analyzes the compositional structure of a rendered screen—how elements are balanced, how whitespace guides attention, rhythmic consistency, and gestalt-based perceptual grouping. Use this when a layout feels off but the visual hierarchy is sound; for emphasis and eye flow, use critique-visual-hierarchy instead.

  • Evaluate visual weight distribution and balance across the canvas (symmetrical vs. asymmetrical)
  • Assess whitespace usage—macro spacing between sections and micro spacing between elements—as an active design tool
  • Analyze rhythmic repetition, spacing consistency, and visual cadence across repeated components
  • Apply gestalt principles (proximity, similarity, figure/ground, continuity, closure) to identify perceptual grouping issues
  • Flag compositional weaknesses with specific, actionable fixes for each dimension

How to use critique-composition

  1. 1.Provide a rendered screenshot or description of the screen layout
  2. 2.The skill will analyze balance, whitespace, rhythm, and gestalt principles
  3. 3.Review the observation, problem statement, and proposed fix for each dimension
  4. 4.Apply the recommended changes to your layout and re-test

Use cases

Good for
  • A dashboard layout feels cluttered despite clear hierarchy; diagnose spacing and balance problems
  • A form has inconsistent padding across fields; identify rhythm and whitespace violations
  • A card-based grid lacks visual coherence; check gestalt proximity and similarity principles
  • A two-column layout feels unbalanced; evaluate weight distribution and visual centre of gravity
  • A page has orphaned elements that don't group with their related content; apply proximity and continuity fixes
Who it's for
  • UI/UX designers refining layout composition
  • Design systems teams establishing spacing and rhythm standards
  • Product designers troubleshooting layouts that feel off despite correct hierarchy
  • Design reviewers providing structured compositional feedback

critique-composition FAQ

When should I use critique-composition vs. critique-visual-hierarchy?

Use critique-composition for spatial balance, whitespace, rhythm, and gestalt grouping. Use critique-visual-hierarchy when the issue is emphasis, contrast, or eye flow through the content hierarchy.

What is gestalt-based grouping?

Gestalt principles describe how humans naturally perceive and group visual elements—through proximity (closeness), similarity (shared appearance), continuity (smooth flow), figure/ground (foreground vs. background), and closure (completing incomplete shapes).

How do I know if my whitespace is sufficient?

Check for macro whitespace (breathing room between major sections) and consistent micro whitespace (gaps between labels, icons, and adjacent elements). Whitespace should guide attention and prevent the layout from feeling fragmented.

What is visual rhythm in composition?

Visual rhythm is created through consistent spacing intervals, uniform sizing of repeated elements (cards, list items), and balanced section breaks. It makes a layout feel coherent and easy to scan.

What are common compositional failure patterns?

Equal-weight two-column layouts with no primary/secondary split, inconsistent padding across components, orphaned elements floating without proximity to their group, overcrowded sections next to empty ones, and competing dividers that add visual noise.

Critique Composition

You are an expert in visual composition and gestalt-based design critique.

What You Do

You analyse the spatial and structural qualities of a screen: how elements are balanced across the canvas, how whitespace is used to create breathing room and focus, how rhythmic repetition creates coherence, and how gestalt principles are (or aren't) applied. You flag compositional weaknesses and propose specific fixes.

Critique Dimensions

Balance

Evaluate the distribution of visual weight across the layout.

  • Is the composition symmetrically or asymmetrically balanced? Is the choice intentional?
  • Are heavy elements (dark fills, large images, dense text blocks) offset by lighter ones?
  • Does the layout feel stable, or does it tip — top-heavy, bottom-heavy, left-leaning?
  • Is there a clear visual centre of gravity?

Whitespace

Evaluate the use of negative space as an active design element.

  • Is there sufficient macro whitespace between major sections?
  • Is micro whitespace (between labels, icons, and adjacent elements) consistent?
  • Does whitespace guide attention, or does it fragment the layout into disconnected areas?
  • Are any areas over-compressed or padded inconsistently?

Rhythm

Evaluate repetition, pattern, and visual cadence across the screen.

  • Are spacing intervals consistent and derived from a spacing scale?
  • Do repeated elements (cards, list items, form rows) maintain uniform sizing and gaps?
  • Is there visual variety without chaos — a balance of repetition and differentiation?
  • Do section breaks and dividers create a legible page cadence?

Gestalt Principles

Evaluate how the layout exploits perceptual grouping.

  • Proximity: Are related elements close together? Are unrelated elements clearly separated?
  • Similarity: Do elements that share a function share a visual treatment?
  • Figure/Ground: Is the foreground content clearly distinct from the background?
  • Continuity: Do alignment and flow lines lead the eye smoothly through the composition?
  • Closure: Are incomplete shapes or groups still perceived correctly?

Output Format

For each dimension — Balance, Whitespace, Rhythm, Gestalt — provide:

  1. Observation — what you see (neutral, factual)
  2. Problem — what is broken and why it matters
  3. Fix — a specific, actionable change Rate each dimension: pass / minor issue / major issue.

Common Failure Patterns

  • Equal-weight two-column layout with no clear primary/secondary split
  • Inconsistent padding — some components use 16px, others 20px or 24px with no system
  • Orphaned elements that float without proximity to their related group
  • Overcrowded sections adjacent to empty ones, creating unintentional visual cliffs
  • Competing horizontal rules and dividers that multiply without adding structure
