Dirtbike sprites

[Colton]

Uh, I wanna make a dirtbiking game sometime.... but I've NEVER tried drawing a dirtbike before. So, I want some critique on this. I know the handlebars look odd.

I suggest you using Anti-Aliasing, shading the outlines a bit and making the tires more circular.

*And the handles *
at least, you can draw a bike better than me; I really need to practice drawing them...
