The umbrella is really nice, and the purple parts are OK. It is not so with the pink parts (a stain in the very front of her chest?). I don't like the skin tone - doesn't look rotten or pale, sunbathed rather with strange shadows. A lot of white unpainted spots: see for example the line on her right breast.

The red is cool with nice transitions. Totally different quality, althoufg some final highlights on the front would help to make it even more attractive. The umbrella, inner part, is not as good as the outer part. The skin tone is better, but the eyes are... strange. They are too bright, popping out from the face. Again, you have left a lot of unpainted spots, even on the dress!
