It really looks and sounds amazing! I first thought it was a bit short for a 4 YEARS project, but after watching it a few more times it just hit me how EPIC it really is... THE ONLY, one thing that I didn't completely like is the story-line. It's just not that original.... And by the way, I don't think anyone really minds if there were some small issues with the sounds.
Keep working on the series, and FOR THE LOVE OF GOD don't make us wait another 4 DAMN YEARS for episode 2 too come out!
