I get some lovely, ethereal vibes from this piece. The colors of the clown and his balloons, and those pink-ish spots on the bottom and in the top-right corner really help to pull my focus around the piece. They also provide a nice contrast with the blue—though, on that note, I kind of find myself getting stuck on the clown as it stands out so much. I love that purple line on the girl's dress. Perhaps more of that would give her more visual weight to balance out the clown?
Overall, very beautiful, interesting piece!
