If you can, please make some videos from the behind yourself perspective, as I think it is the most enjoyable and informative to watch. Then we can see the trajectory of your shots and where they land in the far court, and can have a better idea of their effectiveness.
From the vids you provided so far your strokes look good, clean, but not on a par with what I've seen of professional players. Just my current opinion, and anyway I'm not qualified to judge or comment. But I did enjoy the vids and hope you will post some more from a better perspective.
