I love the expression and the thing she's doing with her hands to try and swim. It looks like her legs are also trying to swim like a squid. I also love how the tentacles are her skirt. Colors are very pleasant too. The knees are a little weird though,ike they stick outwards a bit too much. Maybe that's just because of the color, I don't know.
Overall, great piece and I love the character, there's just that minor knee flaw.
