Well, the piece over all is nicely done. I like the details and pose. However, there are some mistakes. (Forgive me if I sound rude! x3)
First off, The shading is very harsh. I don't know what tool you used to shade, but maybe lower the opacity of the shading?
Also, the tail is a bit awkward. From what you can see behind the legs, it looks as if it was really thick, then dramatically got thin. The left hand should also be shoving behind, otherwise it looks like the arm is short.
My suggestion? Just draw in your own style. Don't try to change it.
Again, my apologies if I sound rude :3
