So here is my version of the Iron Man 3 poster. - [link]
I made 5 posters in all of each of the main characters and a group poster too. I'll start posting them once I shrink them down to size to post on dA. Was really fun to recreate and draw them in a chibi type of cartoon style like I did with my Twilight parody poster a few years back.
Really pleased with the sky and the water effects, I used a bunch of great brushes I found on the internet and can't remember where I got them from, but they really helped to create the effect in the real poster.
Got these printed A4 size and 6x4 and think they look fab.
