Er... The text needs some work... Takes away lots of attention from the rest of the piece.. It'd look better if you sharpened some spots like a bit of his cape and to the left of him that stream of lightish thing... but yea it looks good
I think you need to work on blending and composition. The render as a whole looks too large for the canvas, and it's not very well blended.
I agree the render is a bit too dominating and the eye is more drawn to the text anyway. don't get me wrong its good just needs a little more work
