Alright, so my cab is going to be based on Calvin and Hobbes, and being that it's simple comic art, I thought I could vector it on my own. Turns out, I horribly overestimated my artistic abilities. I've attached the two I want for side-art, just for an example. If anyone can give me a hand on this, it would be much appreciated.
On a related note, I'd like some general art help as well. I want the cab to be a dithered gray color, basically like a newspaper, but I'm not sure how to achieve that look. Any suggestions?
