I downloaded full set :D and your riding looks pretty cool to me, i like your relaxed style.
As someone stated above, try to test Swoard cause your riding is very ECish even you dont stick you hands on snow (which makes your ride look even better :) ).
My only other comment is related files :p take look for other file formats, i recommend wmv or divx, with those you can decrease file size quite much with similar pic quality. If you have MS Moviemaker, it is easy to use and you can define size of final file and it is free. If you have Gates-alergie, then take look for Divx which is also free.
Thaks for nice clip anyway and happy rides.
