As a former biology graduate, this was a fun theme for me. I have always been interested in environmental and ecological issues. The challenge was to find a fine line between realism and stylization when it comes to depict such creatures. Salmon and bonito were somewhat manageable but the crab was a tough one. Since I was not supposed to make up imaginary crabs, it was important to decide which kind to illustrate. A swimming crab was my final choice as I thought it looked interesting in shape and would make a good picture.
Happy holidays to you all.
