Put some sort of exploding light source just above him right hand...
Otherwise I don't see a problem with it as it's your 2nd signature. Very nice work, keep it up!
Its very, very nice. Alot better than your 3rd one, I must say.
If your having trouble placing text, I must say, try the top LH corner.
For a light source, just as Nefarious said, try above the right hand. Could we see the original render?
