This is a pretty epic Brickfilm. The animation is excellent and I particularly like the arrows flying. My only critique is that I noticed the outlines of the green screen, when some of the characters, Iron Man in particular, where flying. However, green screen is a very difficult process and is very hard to perfect. I myself have had made some very challenging scenes using green screen in the past, and I can't say I am hugely pleased with the results. So, with that in mind, you have done a pretty good job. In all, it is a very entertaining and action packed work and I very much enjoyed watching it.
