In MyPaint, each brush behaves uniquely. I can control the brush size and opacity instantly with A,S,D,F keys. Instead of pressing control + Z to get back I just press Z. I think it blends better, too. I can use unlimited canvas if I want to or turn it off when I don't. Lots of advantages over GIMP when it comes to painting, really.
Thanks for checking my stuff now and then man! Appreciate it a lot.
Values are maybe OK but I'm getting a bit too comfortable in that department, there is a lot to improve. My edge management is poor. And colors... no real knowledge, I just play with it until it feels right... I know I need to play with saturation and color compliments, but not much more. I'd much rather be an experienced painter who would just go for an established palette. On the other hand maybe I come up with something remotely original color-wise that way now and then. Maybe. Then there is stuff like perspective or anatomy or skin tones, where I fail even harder. But I doubt it would be fun if I just knew it all. On the other hand ultra high quality finished paintings might please my ego for a while.
I just use GIMP for adjusting or quick textures and MyPaint is pretty OK as far as painting goes.
