Video is deceiving but it looks like you may still have the fear of the speed you would gain by carving in those packed conditions, keep riding and you will get used to it. Those were more groomed hard pack than ice from what the video looks like. When you get more experience you will be able to carve on that surface and you will have to have a higher edge angle than what your using too.
You look like your doing good. My wife is at a similar stage of riding....
