Seems too similar to the official adult Iluvu in pose - something that will always, always put me off of buying a drawing of a Creatu. The tail even flows in exactly the same way.
Also, I'd advise trying some more subtle, all-over highlights. ;o So it's not like, dark, dark, dark, WOAH BALDING SHINE.
Contrast is certainly a good thing when it comes to shading, but it doesn't work when only a few points are in contrast.
Nice texture on the tail though.
