This is more of a personal piece, its a creature design. I like a lot textures in general so I as looking for something than would show textures and be realistic since its the style I enjoy more doing.
So the sketching began, I picked base my self in an octopussy a like creature since it has lots of detail on its skin, shapes and lots to add to this cocnept.
Then with a more refined lineart was time to make decisions about how his skin would be, how he would look like in a more detailed way. Focusing on spots and their location of details.
Some basic shadows and light to the process where detail begans to get heavier based in the line art.
Final render, It got some changes to look more realistic and get rid of the toonish look and adding some colour values to his skin.
