The bases of the splines (or whatever it is you used to make the polyp bits) are still moving around too much. I have no idea how to fix that though (partly because I'm still playing around with that kind of thing myself and partly because I don't know how you actually did it, just how I would have done it). The textures and the movement are beautiful :)
Yaaa I noticed that too. I'm still looking for a way to fix those issues and improve the artwork
