I admit that I was uncertain about downloading ArtRage 2 considering some of the reviews, but I was pleasantly surprised when I tried it out. The response is quite good, even with a decent size image file (30-35 MB). I think the interface is helpful and responsive with a good selection of tools.

I did have some trouble with the blending of brush strokes and would like some more brush options (turning off changing brush size with pressure?). Nonetheless, this is turning out to be a useful application for inexpensive sketching and digital painting.
