Here's a small process pics and a hi-res pic in attachments :3
step 1
sketch (I always love sketches more, I dunno why, now I have a good reason to share it!)

step 2
lines (and this time I decided to leave sketch layer visible)

step 3
flat colors (most of the time it's just black.. cuz I love black and white ok)

...then I adjusted levels and put on "grain" filter in Photoshop and voila!
the result is in attachments
hope you'll enjoy :}
