Thank you very much for the input. I do plan on animating it soon, hopefully, and I can always make the art space bigger for the smoke following instead of rising straight (Thank you by the way, I didn't think about that yet and it would make the animation awkward). I haven't decided if I want to make it moving or just idle. I might delete the motion lines entirely in that case, I added them only because I thought they looked cool. I did struggle with the line work on the tires though, is there a better way to get that shape without making thick, jaggy lines? When I clean them up they lose shape and when I add more they look lopsided as well.
