I always make gifs with Photoshop, and a lot of it is still single-frame editing. Soooo much work. (So I almost never do it either, for the same reason. :D)

I like what you did there!

I'd maybe stop for a bit longer on the last frame, so it looks more like turning around and less like spinning - or did you want to make it look seamless? In that case: excellent job!
