I really like the way you did the scale texture in the middle
However, it seems like the texture gets lost in the bottom right part, and on the face, it looks kinda like you didn't finish the shading - those dark lines stand out too much
Overall, I really like it, though the pose seems a little awkward

I did an edit of the lower right part to show you what i meant:

I threw in those cross-like things that worked for the upper part
Sorry if its a little dark, i was just trying to give an idea
