I saw this video and am very, very impressed. However, I'd like to throw in a few suggestions for improvement, in the hopes that you will make another machinima soon.
First off, I thought the video itself was too long. It had lots of cool action sequences, but overall there wasn't much plot development, so the action felt repetitive. If you could make one where there is a story, maybe even with voice acting, that would be absolutely epic. In that case, the longer the video the better.
Second, that cricket noise in the background was way too loud and annoying.
I want to especially compliment you on the duel between Clint and the man operating the Gatling gun (I LOVE Ennio Morricone's music!) as well as the duel at the end. I hope like hell you will make another video soon, and excellent work on the first one!
