yeah, wtf? i said i'd put the link in and then never did. so here ya go
http://www.odellstudios.com/pics/outline.jpg ... it's not REAL big so you can see each shape but it gives you an idea of what goes into one drawing. you can prolly guess that places like on the hood where the lines appear very thick, you're looking at 3 or 4 lines that close together. I noticed that you saved the wheels for last ... every single person i've seen who is just starting does the same thing. don't be afraid of em. they may seem daunting but you can do it.
i've also noticed 3 distinct styles (maybe 4) of vector art, give or take. some people use a rotoscope style where the shapes are almost blobs that come together to form the larger drawing. From a distance they look very realistic for whatever reason. then there are some people who use gradient mesh and blends and blurs to pull photorealism from Illustrator and the like. i suppose it's for the challenge but i'm not really into that style much. the last group is i guess where i fall into .... using Illustrator mostly as a coloring tool. i dunno, hard to describe i guess. it's not photorealistic but it's also not like the first group where every detail of the source is included as some sort of shape. But there can be all sorts of styles in each of these too. anyway, point is, you can do your own thing and still make it work with vector art. you can say, i'm gonna do this and somehow figure it out. that could save you from getting stuck trying to do what other people do cause let me just tell ya, i just do my own thing with illustrator. there's no secret trick to it, it's just how i use the tool. how you use the tool might be different but i'll bet it works. that's the beauty of it, just because two people use the same software doesn't mean the final products are going to look anything alike, even if it's the same subject.
this has been toooo long so i'll shut up. good luck.
