That's pretty cool. Did you use INKEY$() for the controls, because you can't turn left or right while holding forward. Or maybe that was on purpose.
Anyways, it looks like you've put alot of graphical work into this, and I don't get how you got the reflection in the water to work.
My only tip would be to try to change to 3d skaters, instead of sprite based, then the overall game would look pretty good.
So besides that, good job.
