Hi Mona,
I like your composition and close cropping of the crawfish.
The color contrast is also very nice.
I personally would of liked a bit more focus/clarity on the head...perhaps shooting more from an upward angle.
Glad you participated in the challenge. Look forward to seeing more of your work.

I like the little bit of ive on the mouth parts, I wish it were sharper on the top of the shell. Perhaps you could include a bit more of this interesting looking creature - the legs seem so cut-off.
Top of the crawfish's seems out of focus. Interesting subject matter. Not too crazy about that thin red line in the border: loses its intensity along quite a few spots around the edge of the image.. Plain black would have been better.
Looks more like a lobster than a crab, but they're all shellfish. I might have tried a tighter crop on the eyes. The top of the head seems out of focus.
This looks like a lobster not a crab? I like the photo though... although I would have liked to have seen a little more definition to the ice underneath, especially on the left side.
