@00:17interesting walk, but you can do a pretty normal walk with 24 frames, and just loop it, upper body seems stiff, doesnt rotate and theres no drag and hardly any arm movement, arms just dont go up and down from the elbow, they move back and forth from the shoulder as well, look at ENDLESS REFERENCE on youtube,
no one ever got better from the obvious.. what we need is specifs, details and well though through elaborate comments to learn and improve.. but i understand its difficult to give such information to an artist since one is only able to do so if one knows what he or she is talking about..
Her arms should move more, and something seems off with her legs. Find a reference of a woman walking in heels on youtube. I think it's either not being raised enough when she takes another step. I know she's wearing heels, so maybe watch some videos of runway models walking?
Otherwise it's not bad! Like how her torso moves in front view.
