i'm glad you said no cars, because i suck at them too! haha..
but i am stumped. I agree that futuristic is a great idea, but i always am horrible with coming up with the ideas for these... Just some quick questions to help me:
should the model be high poly, low poly, or your choice?
must it be textured?
Should it just be limited to Maya and photoshop/image editor?
I am stumped with the specific idea though.... so feel free to decide or help me along..
