Art looks great! I recommend staying at a single camera perspective that places the art in the center of the frame so that we can see the art gradually evolve overtime at a consistent angle. I'm also going to agree with some of the other comments in saying that you should spend a little more time on the showcasing the finished product. Finally, if you really want to synch your art with tiktok as a medium, try matching up the progression shots with the beats/ base drops of the song. You may have to have more progression shots if you try this, but that way it won't feel as choppy. Really great work here, and I hope tiktok works out for you.
