Any better? I didn't exaggerate as much as you did, but the movement should still be noticeable, especially on a darker background. It's a little choppier than before, but adding more frames made it look much worse, so I'll leave it as it is for now.

It's just a guess, but I think the atmosphere is different because I didn't colour the tiles by hand - I'm not done scribbling on them yet and didn't want to waste any time in case something changed drastically, so I just added a colour overlay. It looks a bit lifeless, I agree; I'm not going to leave it like that.
I admit I have no idea how to make a tiling wallpaper ornament in perspective. This is the best I can do, I'm afraid. If it looks bad, I guess I'll just scrap it.
