Alright, so recently I've really been into using watercolours and markers. How I like to use them, first I stekct the image (duh xD) and then line it with pen.
Then, colour with one of the two..

But, no matter what pen I've used, it always smudges or whatever, at least a little.

Like with my newest drawing; link

Sure, with the pen I tried on this one, it worked pretty well, but it just annoys me how the ink messed up on the teeth, and the ear's inside..

So, uhh.. anyone know of any good art-specific pens I could get online? ^w^ Something that won't smudge?
