painting without pain, such things happen?

I bought intuos4 last week, wow, I feel that I killed my hand all these years with my very old tablet. Now I just can not tear myself away from a new tablet and I really could paint all day and not feel pain, is happiness!
I played a little with the program Corel Painter Sketch PAD and finished one of the sketches.



I'm trying to find other ways to create animations on the computer because I have always used the Tvpaint animation but it lacks some very important tools (or I just do not know about them). So here a little and very rough test. I'm trying to combine PaintTool SAI and Photoshop, still not perfect and it is very difficult to calculate the timing (. Maybe I need to think about some other program hmmm...
