I've added some tentacles and posed Skerbu which I think make him more interesting. Also started experimenting with Texturing. The texture is a 2k texture . I will create displacement , bump , diffuse, and specular map separately if make time to Render the low-res model in Maya later. For now I'll make the underwater marine background the home of Skerbu for compositing Skerbu.
Thinking about the Fin on his back and the tentacles which can be changed little more later. The color tone has been selected keeping mind that Skerbu is a marine creature.
