Hmm
The craftsmanship of this, like your other work, is excellent. Top-notch drawing, effects, with the textures and all the other things. What bothers me with this one is the actual content matter. Sonic is okay, but the way you drew him here looks odd. It's like a mixture of smooth cartoon drawing and realistic animal combined. You do know that the yellow-y parts of him are also fur, right? And the way his hair just drops down as opposed to up in a razor thingy looks bad, too. The hair on his head has some glimmer on it that just look strange, too. It doesn't even look like his head is attached to the body; there's no flow of his structure. The head's too big, too. His right (our left) arm looks like a 2D drawing compared to the other one that's coated in sweet effects. This whole thing just needs reworking.
