### Ranked Visual Problems

1. **Boxy roof and window frame:** The windshield, roof, and pillars are sharp flat planes instead of the smooth, curved aero shell shown in the sheet.
2. **Plastic toy finish:** The paint is a flat uniform gloss with zero clearcoat depth, roughness variation, or surface dirt.
3. **Flat wheels and tires:** The rims look stamped from flat sheet metal with no deep dish, and the tires are featureless rubber cylinders without sidewall lettering or bead shape.
4. **Missing headlight and grille details:** The front bumper uses basic cutout slits instead of realistic stock car headlight decals and contoured grille mesh.
5. **No panel seams or wheel arch thickness:** The side body is one continuous flat wall with paper-thin wheel cutouts, missing realistic body seams, rivets, and flared fenders.

0. **Blocked on you**: Nothing.
1. **What you changed**: Nothing; completed a read-only visual review of the 3D model renders against the reference sheet.
2. **How you know it works**: Inspected `sheet.jpg`, `final.png`, and `side.png` directly using the image viewer tool.
3. **What would break if you were wrong**: Asset artists might spend time remodeling elements that were already considered acceptable.
4. **What you did NOT do**: Did not modify any mesh, texture, or scene files, and did not inspect any files outside the requested directory.
