Some of my newest sketches:
top left, I wanted to draw a different type of car, than I usually do, so I tried to go wild on the front, I think it went pretty well
top right, A cloth top wich can be put on with buttons, and taken off easily again.
bottom left: It is for the local motors contest, hawaiian theme. the panel in the middle of the front is made of koa tree. But I don't see any function in it, just for fun sketch, but I will keep developing a concept for that contest.
bottom right, some more practise with my markers!
C&C is appreciated
