Hi Kyro6design,
Some nice thoughts in there, and I can see the effort and thought that goes into this, but perhaps there is too much detail that will be lost at smaller sizes or in a single colour? Perhaps less is more in this case. Just a thought, yellow is probably not a colour normally associated with crab, they are generally bright orange when cooked, and yellow tends to not be that appetizing.
Many thanks for your work so far.
