this is a sketch i made that's supposed to be an aston. initially it took some influences from the dbr9, but it looks more styled after modern japanese concepts like the supra concept and gundams.
not bad! perspective looks pretty good, proportion wise the start of the windshield could be pushed rearward to give the car a longer more Astony hood. Don't forget about the rear there, its kind of fading into nothing. Tips for lineweight: go heavy on the window surrounds (indicates rubber surrounds) under the car and any surface you could theoretically wrap your fingers around (that side scoopy thing on the front fender)
also ditch the lined paper, just grab some printer paper to sketch on when your bored in math class. good work, keep going!
Looks good overall, but the windshield edges and stuff look a little lumpy. It may look a lot sharper with those cleaned up (Besiudes, you can't bend glass like that anyway).
thanks for the inputs, i agree with the windshield, since it's an aston it's a front engine with a long front end, and the lumps on the windshield was kind of not too realistic to begin with they were kind of there to add flow. i'll try to improve my line work and try rendering my sketches.
