Starting with small thumbnails to quickly capture the ideas and possible compositions, old-school pen on paper. I like the idea of someone with a flare or torch (like the Olypic athletes), taking a jump from a cliff, but not falling down and keep running instead. 

I like both the side view and the one where we can see the character back, but decided for the side view where it's more obvious that he is in the air and not falling down to the ocean.
