Those look good. They have an loose style to them. Does that style carry over to your more complete works? I find spending a long time on a piece can kill the fluidity, as well as get kind of boring to paint.
Actually, looking at them after a bit, the top one reminds me a (tiny) bit of Gustav Klimt. He also put a great deal of detail into the face and exposed body of his subjects, but reduced the clothing and surroundings to a very abstract set of forms. It might be something to consider with your future work.
Can't wait to see more!
