4th place Car #1 - GTO Street Freak

Excellent job on the interior (dash board gauges are especially well done). Nice work on the engine details, spark plug wires, cables, etc.
Unfortunately, the white edge on the Reaper decal is very obvious and a deal breaker. In the future you can try using some fine sandpaper (220 grit or higher) and sand down the paper edge until it is tissue thin.
I also noticed the unpainted white plastic wheel rims on the underside of the model. That's another element that sticks out. It attracts the viewer's eye simply because that's not what color it would be in the real world.
