I think it looks a little bit weird that the mane (is that what the hair is called? D fades a way. I'm not a huge fan of black/white pics, and I also think it gets a little bit plain. The effects are taking the focus away from the lion, and thats a thing i would have change. You could blur the effects, og sharpen the lion. Or you could put on some new effects which "work" together with the lion. Giving it more focus.
Also, you should work on the blending. Get some smoke, or effects in front.
