yeah, 1st one seemed high for sure, the rest were closer, but seemed high.
I say seemed because the camera angle sucks (low perspective; looking up like an ant would view it) so its hard to tell.
Not trying to be an ass, but bunching the (black) shorts up into a diaper only masks the landmarks on your hip/body that we are looking for.
That's not helping, we don't need to see your bare thighs, as nice as they are
Squatting naked would be better.
(or just non-black shorts or tight leggings, etc)
Other than that, everything looks ok.
Its definitely not a strength issue.
