hi Riff,
As a future improvement to consider,.... The Down Spar end-caps on top should be flush along the leading edge, sticking up is sure tangle point some day when you are all slack lined and spankin' it.
and maybe a little more curvature built into the leading edge (seems pretty laser straight in the video compared to other kites shown) so it "cups air" better. Try a couple of inches (2) down from the center (on each wing-tip) so the curve is built into the leading edge sleeve without a set of sticks inserted,
your kites look good in the sunlight,
editing could take out JH in the foreground, Ha!
