You don't seem to be around anymore, but I still remember this picture when searching for Kingdom Hearts Behemoth stuff on deviantArt.
I like how you can see how his purple color, horns, bull anatomy, and imposing size say that he's still a Behemoth. However, I like those sleek curves he has and that vaguely humanoid musculature. He looks so buff! Those hands and feel look very feral, though. Those sleek curves make him look like he's flying. The reds you gave him accentuate his purple body. His red horn tips looks like they've done some damage. I really like his red mane, but that elbow fur looks odd. I even notice a bit of that Heartless mist coming from his wings. I also see that you've used color theory, since red is close to purple which is opposite yellow, the color you used at his eyes. There's also the way you've shaded the back of his right arm and the base of the tail, giving depth.
