I've been meaning to do this for some time.

The differences between Dipper and Kit Cloudkicker become much more apparent when you put in the coloration.

I've been getting better and better at "inking" sketches done for me, and coloring them. Yeah, except for the shading in the crotch of Dipper and the shadow below him, there really isn't any depth to it, but I'm still learning.

Initial sketch by  cirrus

Berzier curve "inking", re-lettering, and coloration by me, using paint.NET, which is available FREE at http://www.getpaint.net/
