Really nice vid. Just gonna be honest and say that your replays are the ones that need work. I realized you have just started in this and considering that, they are great. As I said before, just arm DM's aren't enough. A chest DM or a decap is much preferred.

Ducky, your replay had some decent manips, but the dm is where the replay, sort of, had a downfall. Personally, I like chest dm's, decaps, or boomhits.
