Ga-ross! My dad however would race you to the bottom of the pot! :) - that said, I think this photo is a little too dark, but 'thank goodness' we can still make out the little critters. :P
I think this would have been a better shot as a macro, or at least more of a close up -- especially right around that area on the right with the lighter crawdads/crayfish. However, I also recognize may not be possible with your camera, nor would the idea of transition have been quite so clear.
I think the idea of transition would be more clear if you would have actually showed the proces of cooking. Now it just looks like a bucket whith cooked shrimps. But maybe you had another transition in mind.
Ack Lobsters. Would have been cool if you could have gotten really close. Or maybe a picture of it squirming as you drop it into a pot full of hot water.
ewwww! This gives me the creeps! Technically it is not a bad shot, I think it could have been better if your framing was not quite so tight, more impact would have been the whole bucket
