Eidolon is pretty awesome, and so is this art. I especially like the one with Leviathan, due to the fantastic positioning. It really makes Leviathan feel like the threat he is, but at the same time the character going “Into the Storm” (as the piece is titled judging by the image url I was given) still looks powerful, not helpless. Being Eidolon, that makes sense.
