i think it's a pity loading retouching vids on youtube.. you can't see any details there.. if you've got a good capturing program (full screen size) try
http://www.vimeo.com its as simple as youtube, but way better (= bigger).
To Your vid: It's not exactly informative.. It's more a "look what I can do vid" - nice to watch, but nothing to learn there.. I prefer commented technical vids. but pretty good result, though!
