 review:
   strengths:
-  - Excellent spec compliance with all required features and correct layout conventions
-  - Realistic geological data using actual Western US formation names
-  - Good variety of lithology patterns approximating standard geological symbols
-  - Well-structured plotnine layer composition with clean theme customization
+  - Excellent spec compliance with all required features (6 lithology patterns, formation
+    names, age labels, unconformity)
+  - Realistic geological data with real Western US formation names and plausible stratigraphy
+  - Strong data storytelling through the red unconformity highlight at J/K boundary
+  - Clean well-organized code with good reproducibility
+  - Custom color palette with thoughtful geological color choices
   weaknesses:
-  - Formation and age label font sizes too small (10-11pt)
-  - Siltstone pattern too sparse and hard to distinguish
-  - Color contrast between siltstone and shale insufficient
-  - No visual emphasis or focal point for data storytelling
-  - Title at 22pt slightly under 24pt guideline
-  image_description: 'The plot displays a vertical stratigraphic column spanning 0-180m
-    depth with 10 geological layers. Each layer is filled with a distinct muted color
-    and overlaid with lithology-specific patterns: sandstone (yellow with stipple
-    dots), shale (gray with horizontal dashes), limestone (blue with brick pattern),
-    siltstone (light blue-gray with short random dashes), conglomerate (salmon with
-    open circles), and mudstone (brown with dense horizontal dashes). Age labels (Late
-    Cretaceous through Triassic) appear on the left side, and formation names (Frontier
-    Fm, Madison Fm, Kootenai Fm, Morrison Fm, Sundance Fm) in italics on the right.
-    The y-axis shows "Depth (m)" increasing downward with ticks every 20m. A horizontal
-    legend at the bottom identifies all 6 lithology types. The title reads "column-stratigraphic
-    · plotnine · pyplots.ai" in bold at the top. Background is white with subtle horizontal
-    grid lines.'
+  - Formation labels (14pt) and age labels (13pt) slightly undersized for full resolution
+  - Shale and Mudstone colors too similar in lightness for colorblind accessibility
+  - Horizontal canvas space underutilized with wide x-limits
+  - Library mastery could be improved with more distinctive plotnine features
+  image_description: 'The plot displays a vertical stratigraphic column showing 10
+    geological layers from 0 to 180 meters depth (increasing downward). Each layer
+    is filled with a distinct color and overlaid with lithology-specific patterns:
+    yellow with stipple dots for Sandstone, gray with horizontal dashes for Shale,
+    blue with brick pattern for Limestone, light green with short random dashes for
+    Siltstone, salmon/orange with open circles for Conglomerate, and brown with fine
+    horizontal dashes for Mudstone. Formation names (Frontier Fm, Madison Fm, Kootenai
+    Fm, Morrison Fm, Sundance Fm) appear in italics on the right side. Geological
+    age labels (Late Cretaceous, Early Cretaceous, Late Jurassic, Middle Jurassic,
+    Triassic) appear in bold on the left side with bracket lines. A red wavy line
+    at 95m marks an unconformity between Kootenai Fm and Morrison Fm, labeled "~ Unconformity
+    ~" in red italic bold. The title reads "column-stratigraphic · plotnine · pyplots.ai"
+    at top. A horizontal legend at the bottom shows all 6 lithology types. The background
+    is light gray with subtle horizontal grid lines.'
