Ashe,
Very thoughtful of you, but youtube is working as intended now in Thailand after me and a few people went to the department of IT and b!tched from dusk til' dawn.
As for the video;
Very nice footwork. Going to the sides like that is very useful in avoiding incoming strikes, and going from orthodox to southpaw and back again guarantees mind-f*ckery (excuse my cussing

).
Your techniques are crisp and very accurate I may say.
One thing I have to advice however, is that you need to keep your rear hand closer to the chin.
Other than that, good display of technique, power and speed. I have to add that you make a good example of moving around the speedbag, I see waay too many people who stand still while working on the bag. It's like their legs are stationary when they should be moving.
Good work mate.
