I spent this session refining details on my hand. I take extra care in getting this right.
One negative about painting on paper is that it does tend to warp a bit on some ends. I could tape it down but I also want to paint all the way to the top and bottom edges. You can see in the detail photo how much the paper is bowed away from the support. Of course when it is frame, if it is ever framed, this will fix this issue. But during painting it makes things a bit difficult.
