### Verdict
**REVISE**

### Prioritized Findings

1. **`FT-TEX-01` Flat toy-like shading and light pastel green hull**
   - **Visible symptom & location:** Entire main hull, turret, and track suspension girders across all renders (`final.png`, `side.png`, `states.png`). The paint is an unweathered, pale mint green with visible vertical procedural streaking/wood-grain artifacting rather than dark matte French military olive drab with edge wear, dirt, and chipped paint.
   - **Observed vs suspected cause:** Observed flat, clean pastel surface without metallic or roughness breakup. Suspected cause: procedural diffuse color `#9eb38c` lacking PBR normal/roughness detail maps, occlusion, or steel edge wear.
   - **Suggested correction:** Match `sheet.jpg` material palette (`MATTE PAINT` dark drab green, weathered steel, grime). Bake ambient occlusion, edge wear/scuffs, and subtle surface micro-roughness.
   - **Measurable acceptance criterion:** Diffuse hue matches sheet reference RGB range (~`#4e5445`), with roughness variation and visible steel edge chipping around rivets and panel seams.

2. **`FT-GEO-01` Oversized, hollow tail skid and incorrect truss geometry**
   - **Visible symptom & location:** Rear trench skid in `side.png` and `final.png`. The skid extends too far upward and backward with oversized, thick lumber slats and an open box-like rectangular frame that sticks up well above the rear deck line.
   - **Observed vs suspected cause:** Observed angular, bulky frame with a massive horizontal upper beam. Suspected cause: missing the curved steel truss profile clearly shown on `sheet.jpg` labeled `CURVED TAIL SKID`.
   - **Suggested correction:** Rework tail skid geometry to follow the tapered curved steel leaf/plate profile in `sheet.jpg`, lowering the top rail flush with the rear engine slope.
   - **Measurable acceptance criterion:** Skid matches side-profile silhouette in `sheet.jpg`, curving smoothly upward from hull lower brackets without towering boxy uprights.

3. **`FT-TRK-01` Track sag, suspension girder, and pitch mismatch**
   - **Visible symptom & location:** Upper track run on both sides (`side.png`, `final.png`). The track belt floats in a rigid straight slope directly over the return rollers without the distinctive historical guide rails/girders hugging the track top. The idler/sprocket wheels appear plastic/flat brown rather than weathered dark wood/steel.
   - **Observed vs suspected cause:** Observed rigid linear track run and overly chunky separate rectangular pad blocks. Suspected cause: track spline or array lacks top run support beam, sagging, and guide tooth engagement.
   - **Suggested correction:** Recalculate track shoe width and pitch to sit flush on return rollers; add the upper track channel beam and realistic steel/wood composite texturing to front idler.
   - **Measurable acceptance criterion:** Upper track rests on the support rollers/rail without floating gaps; front wooden idler shows banded steel rim and dark weathered timber spokes.

4. **`FT-DMG-01` Burnt damage state is a flat black silhouette with detached solid turret**
   - **Visible symptom & location:** Destroyed states in `states.png` (bottom row, panels 5 and 6). The tank turns into a monochrome matte charcoal silhouette without scorched paint transitions, weld cracks, or shot scars. In panel 6, a solid enclosed cylinder ring sits on the hull deck while the whole turret lies intact on the ground.
   - **Observed vs suspected cause:** Observed uniform charcoal diffuse override and a solid plugged turret hole. Suspected cause: whole-model material tint to `#1a1a1a` without burnt texture masks, and turret hull hole has no hollow internal geometry/open turret ring.
   - **Suggested correction:** Carve a hollow open turret ring into the hull top showing internal structural framing/scorched metal edges. Apply localized burn gradients, rust, soot masks, and visible penetrated shot scars rather than global flat black paint.
   - **Measurable acceptance criterion:** Hull exposes a hollow turret opening; damaged mesh shows localized deformation, punctured shot craters, and multi-tone soot/rust scorch marks.

5. **`FT-GEO-02` Gun mantlet and turret proportions too blocky**
   - **Visible symptom & location:** Puteaux 37mm gun mount and mushroom cupola (`final.png`, `side.png`). The gun mantlet is an untextured extruded square block with sharp 90-degree corners, and the barrel lacks stepped taper and collar detail shown on the sheet. The vision slits on the hull are simple extruded holes without visor plates.
   - **Observed vs suspected cause:** Observed primitive rectangular boxes for mantlet and vision ports. Suspected cause: low-poly blockout primitives left unchamfered/unmodeled.
   - **Suggested correction:** Bevel and shape mantlet housing with rounded casting profile, add barrel sleeve collar, and add front driver vision flap doors per `sheet.jpg`.
   - **Measurable acceptance criterion:** Mantlet exhibits cast curved profile matching `sheet.jpg` front/hero views, with distinct barrel collar and hinged vision visor geometry.

### Standard Report

0. **Blocked on you**: nothing.
1. **What you changed**: None (read-only critique performed).
2. **How you know it works**: Read and visually evaluated all 4 required render images (`sheet.jpg`, `final.png`, `side.png`, `states.png`) directly.
3. **What would break if you were wrong**: An asset team could spend cycles reworking geometry and textures when a simpler material re-bake might have sufficed.
4. **What you did NOT do**: Did not edit files, inspect geometry node trees, or run test renders.
