Nice shots.
I believe the shrimp/fish shots could be improved by controlling the background better. In the shrimp shot there is a bright object lower left. I find this distracts from the focus point (shrimp). Similarly the two clowns have that very bright candy cane behind them. Photo editing software could be your friend here.
The black clown is a tough subject on a black background. It's head blends into the background. Getting more light to the background would help. Also a bit more exposure might bring out it's eyes. Kind of spooky w/ no eyes!
The focus seems a little soft on some. Perhaps my glasses just need to be cleaned!
Hope these comments don't seem to harsh. Overall very nice.
