I think I'm more fond of the new art...It looks...more appropriate, plus it has the FFQ in question interacting with what appears to be balls of light, which can be assuming to be the Fireflies she creates. IDK about the anthromorphism, of directly giving her a face, but ehh.
Sapphire Charger I like the new art on. See, the old charger, to me at least, had all these weird spikes and curves to it that made figuing out the shape of it (to me at least) very difficult. All I really could tell was that it was a quadraped creature.
And a nice touch to the new gravity creature art: The creatures have a recurring theme in the background of their world...Almost suggests with a bit of filler work, Vrt could do a sort of 'wildlife savanna' picture with all the gravity creatures hanging out together (maybe in a very early stage of chimera creation?)
Lycantrope looks a bit more like a proper werewolf which is nice.
Pufferfish now looks more specific to being an aquatic creature. Yea, old one had fins, but that thing also had legs that pointed it more toward being amphibian than aquatic...
