I like cropping, rotating, and playing with layers. Sometimes I also like to play with the colour adjustment buttons (but I don't do that often; somehow it seems like a betrayal - I don't know why :))
I'm especially into cropping. Fully sized paintings simply seem boring to me (and I'm only talking about my own paintings here! I love the fully sized works of my colleagues!). Maybe it's because of my lacking arrangement skills or something, but I get fascinated about details.
Right now I'm having a rough patch in my personal life. A midlife crisis, possibly, and a (hopefully not permanent) loss of self-confidence as an artist and a human being. (This often happens to me in spring, though, so it might be over by summer :))
While Waiting for the Sun, I'm painting my anxiety on paper.
