ok first of all (skip the lensflare), it is all blurry and its hard to get any focus. the place where his body meets the cape (at HIS right side) its too much contrast, the cape is too bright there, cant since u have the light sourcre from behind (if it is not very thin that is, but it looks rather thick). it is really hard to see what is going on with that armor of his, u really need to take a look at it and make it clearer. else its quite neat like the angle and pose
Nice start! Lose the flare. His right forearm is too big, with that much "light" emitting from his left arm/hand/weapon this image should have a lot more contrast, face looks nice but check the shape of the head, add a background and tighten up your lines a bit. Nice composition, and color selection. Keep at it.
I agree man, lose the lens flare (or at least tone it down substantially). Even with the glare, his left arm seems a bit gestural, not too much definition in there, amkes it look a little akward with his right arm having such a definite shape. Looks good though, reminds me of Conan the Destroyer
