It's a great start. Next you should make a hole in the hood and model the blower on the engine Also blender destroys smoothing groups so the best you can do is edge split everything again. Won't look as good but that's all modders can do at this point
Here's my attempt: It is UV mapped but I haven't bothered texturing it or normal mapping it - I simply don't have time It is Jbeam'ed and deforms, but has maybe 6 more nodes And it is modelled by me in about 5 mins whole thing took about 45mins
Apply edge split to it and it'll look better, also will look better with proper materials and UV mapping
So do you have a tenitive relase date? I love gaming with hotrods of all kinds. Keep us posted on progress. I hope you add some good sounds as well.
