good work, im a snowboarder and have been for the last 5 years.
the thing i find funny is the design concepts.
the character doesnt really fit the description of snowboarder
which made me laugh. blue suit with yellow stripes, goatee and sunglasses
haha.. i guess you dont need to look a certain way to snowboard.. but from a snowboarders point of view its pretty funny. well im not gonna
tell you what to make him look like. maybe replaces the sunglasses with goggles
tho. the snowboard seems a big too long. and its a bit plain.. a stripe..a graphic would be much nicer.

and another thing that was funny is the video. it kinda takes the word 'extreme'
out of your title. lol

one week, very impressive.
if you need any concept help
or anything, gimme a shout.
