Yesterday we saw some of Marvel's concept art of Chris Evans as Captain America. I liked the designs that they came up with and I can't wait to see what it looks like brought to life on the big screen. Today some concept art for Marvel's Thor was leaked online, this art definitely isn't as cool as the actual photo of Thor that was released. This Thor art is clearly photoshopped. It's not the best photoshop job, but it's concept art, which is always a bit on the rough side. What makes these images interesting is the fact that it's the first time we've seen movie Thor holding the legendary hammer Mjolnir. Check out the images below and tell us what ya think!
