This piece has a wonderful colour scheme; the warm colours give just the right feeling to the work. Not only that, but the subjects are well drawn, with just the right amount of obscurity.
The only fault I can really see is that it's a little bit hard to distinguish at first where the man's sleeve ends and the girl begins, and the angle of the girl's face. If you could thicken the lines just a touch or otherwise strengthen the shapes there, it may improve it a little.
That little tidbit aside though, the shape of the picture relative to the subjects helps keep a sense of closeness that is just perfect. An overall beautiful piece of art that I was glad to see.
