I also coloured in that picture of an Argonian I did. Badly.
While I was at it, I also did that barnacle thing. Badly.
The trouble with me and image programs is that I don't like to obscure the lines I drew on paper, because then I'll have to draw them again on the computer. This means I keep the paint opacity low, but then I end up with quite a watery look, with the colours paler than I'd like.
