Here's an awesome collection of new concept art for films such as The Avengers, Green Lantern and some other character and costume designs for X-Men: First Class. The coolest art in the set though is some awesome keyframes for The Avengers from concept artist Rodney Fuentebella. I'm not really a big fan of the X-Men: First Class art from artist Thomas Whitehouse - those costume designs are pretty bad. Then artist Steffen Reichstadt released a few different versions of Stel, the Grendan Green Lantern. Look over the concept art and let us know what you think!
