[Portal 2] speedrun of Smooth Jazz in 27.08s

Speedrun of the Portal 2 challenge mode chamber "Smooth Jazz" in 27.08s. Ranked ~106 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... ). I am fairly new to making videos and speedrunning, so any feedback, tips, advice 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). Also, if you have any questions, concerns, suggestions, feedback or anything else, feel free to post either in the comments or pm me. I will try to respond (if appropriate) as quickly as I can.
