nice work, try smudging the crab a bit ( make a new layer, then select sample all layers and smothing him out a but, and clean the edges, and add some highlights with a layer of white smudges with adjusted opacity. I just did a video for turning something into chocolate, if i can figure out how to post it to the tuturials ill let you know the link great work!

Looks good, some parts, like the leg on the right are missing a bit of chocolate, but for a first try it's good. G'luck!
