Good stuff! How did you get a "dissolve" in the approximate shape of an Aerobe (e.g., at about 7:00 in)??
You're good at damping out the "rocking" (stalling and diving) at the top of a stall, but you usually let it go for a few more "rocks" than I do. (I also think you're not stepping on your line often enough!
Also, I THINK you've got the spreaders on the back/top/away side of the kite, no? In winds this light, I think I'd put 'em on the front/bottom/toward-me side, so the sail could billow smoothly and maybe glide a smidge better.
