You seem really good so far! I love your movement at the canter.
But, your arms seem too straight. Your elbows should have more of a bend in them.
And your heels should be pushed down more consistently, especially in the second video, where your toes were pushed down. It's kind of hard to tell but I would shorten your stirrups maybe a notch, as it seems that (especially when you don't have your heels down) they are slipping off your foot. Also, your leg position seems to stray further back behind the girth than it should. I would work on riding without stirrups to help strengthen your legs.
You also seem a little stiff to me. Remember to relax, breathe, and smile!
