Car troubles

I am trying to make a really nice sketch (concept like) of a friend's car. I have erased and redrew, the erased and redrew wayyyyyy tooooooo mannnnnnny times *fail* I am still battling on that. On the sucky side of things, I left my laptop charger at school, and my laptop died, so it's hard to work without it (i need music, refs, and inspiration) ... ohwell.

Anyways, any insight or help or anything would be fabulous, i need to find some books and good tutorials. All redlines on the images accepted, infact needed lol.

here's a whiiiirrrl of the process so far...







Still working my ass off with this, I need to get myself sorted with the vanishing points and really give that flat looking car some real volume.... then after it's all nice nice lineart.. I am going to try out my copics for the very first time *fear*
Good thing for light tables (incase i mess it up and need to try again hahah)

OK... keep yall posted ;)
