I like what you were going for. For the most part it turned out pretty well. There are a few places that are a bit oversharp/overcontrasted. Easy fix. Also it feels like it needs a little less FG than it has. Empty space could be a good idea. Overall I like it. Minor fixes.
I like it. Good flow and focal point, would agree that a little burn would help with the depth. Otherwise, kudos
You guys pretty much said what I was thinking. Just needs a bit more depth, and I think if iron man stuck out more, it would be pretty awesome.
