I agree with @sparksofdawn about the stick-o-doom handle, but it also looks a little transparent in the body where it overlaps her cloak.
If I were to be super picky I would also mention the ripples from her leg and the angel resting in the water. It looks a little too sharp and empty. Maybe just add a few more lines like you already have and then use smudge or liquify on the parts that are under the water.
Overall I think this turned out great. I wouldn't be surprised at all if this is one of the winners. Its an interesting idea, a cool design, lots of personality, and painted very well. Good job!
