Finished up painting another mermaid this morning--in the Brushes app on my iPhone. This one's a little manga-ish, and have I mentioned how much I love the layering features in Brushes? I don't think I'd be able to do shading anywhere near as subtle without layers.
Are you a Brushes user? I'm wondering how many use a stylus? I bought one, used it for a couple paintings, about twenty minutes and have never picked it up again. I'm doing all of these drawings, sketches, paintings with my fingers. Took me a bit to get it down, but I use the tools--brushes sizes, textures, undo, layers so much that I just couldn't work with the stylus--holding it and constantly shifting to change brushes, transparency, paint colors--all of this is so much easier with your fingers than with the stylus.
