You've got something going on, definitely. I can see a part of a classic gag - man goes snowboarding or sledding, makes a jump, crashes through a roof and into the fireplace.

If I had to suggest an improvement, it's to make it a little longer, but not just for the sake of a longer runtime. As I see it, this part could be the last third, specifically the punchline, of a short story. The other two thirds could be spent showing your character that he's a risk taker and he initially succeeds, but then bit more than he could chew.

This is just an example but this is something I'd see: Character goes boarding/sledding and ignores a warning sign of some sort -> Character performs a first jump successfully, gets cocky -> Character performs second jump, ends up crashing in the house.

Feel free to play around with that, or to experiment with other ideas.
