First off, in all the 2D Zeldas (except Four Swords), Link spins from start to finish, with at least four frames of animation
Second, the first spin, then going back to a standing position as he falls is a good idea, but a horrid way to execute it for all quests. I propose a 3-frame ascention animation, a two-frame apex animation, and a three-frame falling animation. Enabled by quest rules, of course
My first suggestion is seperate from the second, as the four frames would just loop like they do in the GB Zeldas. The second would allow Link to have shadow pixels in his main sprite, which with the current setup, looks tackey
