Avengers: Age of Ultron
I drew this picture a while back, but totally didn't realize that I have not featured it on this blog. I was inspired by that one scene in the beginning of Avengers: Age of Ultron where they all jumped into battle in slow motion. It was a really cool image that stuck with me. Incidentally, the biggest flaw of the picture was that I did not do enough of a job separating the different figures apart. So Iron Man looks sort of like a part of Captain America's bike and so on. It is not as clean of a picture as I would have liked.
Still, it is a really cool image and the speed lines I added really make the whole thing look dynamic. Here is a screenshot of the scene from the movie for comparison.
