[Portal 2] Speedrun of Turret Intro in 21.16s (rank 54)

Screw the cube throw on this map! lol. Also, I think there is only one more video I have that isn't top 50. Speedrun of the Portal 2 challenge mode chamber "Turret Intro" in 21.16s. Rank ~54 on the steam leader boards (steam leaderboard rankings are approximate as they do include some illegitimate times). Leaderboards can be found at http://steamcommunity.com/stats/Porta... Any feedback, tips, advice, criticism etc. in regards to either the video or the game play itself is greatly appreciated (and feel free to be harsh, I can take it). If you have any questions feel free to ask in the comments or pm me and I will try to respond asap.
