Good point! I didn't even notice. Here's a mostly-fixed version.
really smooth,
however you've got the foreground limbs almost in tandem, like 2 sets of bipedal legs walking in synch, noticed it instantly because I've made the same mistake already.

that was quick! legs are much better
but looks a tad limpy maybe the head could use a subtle up and down bob at some point it seems to be out of synch with the body, and the wing animation looks fluid but reads like a cape, before it had a strange fluidity
overall good job
, I know how difficult animation is, and especially at that scale.
