I would like to congratulate you on making this work of art as incredible as it is, you can't find anything wrong with it! The approach you have implemented is quite ground-breaking. I knew you were very talented the first time I saw you, and this image here is proof of it. The shape of the crab is something I haven't seen before, the use of colors with low saturation on most of the image gives it a nice contrast. The background's quality doesn't compete with the rest seen in the whole of the artwork though, but I'm sure you did that for a reason. I would like to add that it has been a pleasure to invest some time in this critique for you and I think it will help you to increase the quality of your magnificent pieces of work, cheers!
Just like the Snowmancer, the way you've shown the image is so fresh and imaginitive, it's great to look at. Your work is never a standard Fantasy pic, even if it depicts a standard Fantasy theme or person.
