Nice work, I like it a lot!
Question, where did you get the vector graphics? Did you trace them yourself in Illustrator?
I can get around in Photoshop pretty well, but I *suck* at Illustrator. I don't even know how to "trace" in it.
Either way, I figure it's not too early to start thinking about graphics once my cab is built. I was going to use some "stock" art, but once I got to thinking about it, why not personalize it since I'm going to all the trouble of building it from scratch?
So far, I'm thinking on a black and red themed cab, that's about it.
Thanks for your help!
