I'm liking all the colors in this piece. They are so bright, and shiny looking. It gives a pretty mood, like an opal. The composition and movement in the picture is good, as well.
A suggestion I have to offer has to do with the female. She sticks out because she is the most human of the bunch. However, she seems unhuman at the same time because her face looks a bit lifeless, and her proportions seem off. Her head is a bit large. Her arms are a bit short. And her scarf seems so tightly wound it could suffocate a woman.
