It's Nova Surfboarding! (I soooo wanna try this sometime!! xD)
Amazingly, I did this quicker than most pictures and it only took about 12 layers rather than 20-something.
I scanned this in this morning and spent about 5 hours doing the lineart, colouring and applying the shading. I made the waves clouds and sun with the airbrush tool, but they are a bit odd.

Please don't crit too much on this one though, it's my first time trying to do a surfing position and the legs look odd, I know. xD
