Hello everyone ! 
I made this artwork recently as part of a french 3D contest which theme was Here comes Summer.
I decided to depict a ghost crab because of its particular look, with its eyes coming out of his main body, and also because I think itās a good way to symbolize both summer and exoticism. At the end, I wanted to achieve a postcard look by deteriorating the picture in post-process.
Iām not very familiar with organic modeling / rigging, so this was a great exercice and to improve my skills. Even if I would have put more details into the crabās face because it lacks volume and details in my opinion, but I chose a not ideal workflow and it was kinda hard to do any modification to the main mesh. So, I decided to move on to other projects. I tried using some motion blur especially because there are seagulls in the background but the depth of field is so intense that it just looked like a pile of blurry pixels ! 
2400 x 1350 render without the postcard look
