Good job so far! Way to record yourself, I know sometimes it can be intimidating! I'm going to have to agree with the arms thing-having a steady contact will be so much more comfortable for you guys. I remember in my first few lessons I wasn't getting it, so my teacher stopped us and grabbed one rein between the bit and my hand and showed me how much I should fell all the time. and she showed me how my lack of contact was jabbing the horse in the mouth every time the reins were kind of flopping around. I guess what I'm trying to say is you are going to have a breakthrough about your hands! and it will be exciting. Many horses really enjoy having that elastic contact (I can't say all, because I don't know too many horses) and very obvious direction. Maybe next time, think about one pound of resistance, and it may help your hands to stay with the horse's movement and potentially get rid of that head tossing you wrote about. But seriously, good for you! Check out Erica Poseley on youtube. She has some videos about independent seat and her elastic contact with the reins video is pretty cool! Have fun!
