I used Photoshop CS6

I traced the lines and shaded it myself

the shading is good, you should try not tracing next time tho just to give yourself more of a challenge!

who the fuck is axl rose lmao

she looks weird as hell lol

he should be fan of gun's and roses.
Axl rose is a man.

nice stuff, try working on blending better, I see that your value transitions are rough.

nice work though.

thanks for the comments guys,

dengue: what do you mean by "value transistions"?

veoo: its the lead singer of guns n roses, a famous rock band, and i do art for fun, but i dont think drawing my own lines is fun xD

the gradient of each value to another is dirty, try smoothing.
