Did this for some weekly contest thing, it didn't quite turn out how I wanted. I did it on regular sketchbook paper instead of bristol, so the ink washes wrinkled the hell out of it.

Just playin' with ink and carbon pencils (and super quick digital colors). They make a good combo, but it seems that the pencils will actually gum up if you try to draw over thick ink lines, dry or not. I've been using Speedball superblack india ink, I'm wondering if the brand might be the culprit.
