Ok, i get the idea what your trying to do. But in all honesty it is awful.
-The lighting is off, if you wanted an effect like this, only the hand, the eyes, the wings should be slightly exposed and everything else a nice flat black.
-The eyes are blue? so is it a daemon or angel i don't understand yet the wings are red. Make it consistent by using red eyes.
-The expression on the boy's face is not convincing at all.
-Remove the straps on the wings in photoshop to make it look semi realistic
-and just like everyone else said, the hand is overexposed
just my two cents
