While I certainly won't deny that both of them are cute, I can't help but feel like the salamander and undine elements are sorely lacking in these two girls. One has nothing but little horns and the other one might as well just be an elf. Surely the artist could at least add some scales, or fluid hair, something to make them more inhuman?
At least bikini armor pole-dancing is quite a unique scenario.
The Undine has gills but thats it. Salamander should have had a tail...
