I've been using GIMP for things like inking and coloring for most of my drawings. For this pic, though, I used PaintTool SAI, which has a Linework Layer option that I thought was pretty cool and thus put to use here. ^^ I considered drawing Uncle Skunklin sat in his rocking chair from a side view instead of the angle I went with here, which I imagine would've been somewhat easier for me to draw.
