i think you could've put the effect over iron man himself a bit, but otherwise love the compo, nice lighting, good work overall ^_^
Indeed, great lighting.. Better than what I could do lol.. The BG is a little dull, like the sky seems faded, it doesn't have attractive coloring. I would replace the BG with a more alive sky. Some smudging around the edges of Iron Man would be great, to simulate that effect of all of that force flying downward, ya know
Ok, I tried to work with it a bit. Make it a bit brighter and add some smudging to the body to make it have more motion. Ignore the text...it was a bitch on this sig for some reason.
