I'm pretty sure you're on my friends list on live for this purpose, I can't remember what the outcome was, I smoke too much ha ha. I liked the skating alot, tune went well with the skating, the filming I would say needs some work, just a pointer think about where your filmer is standing, there's one bit he'd be floating above the canal and your ender he floats down the massive stairs... But filming's easily solveable.
Pop up on CNBS page (details re am search are on there) n we'll get at you.

Peace
