I love the moss, the water, the lighting, Stang's hair, Claude in the background, all of it! The moss really looks like moss, the rocks look so realistic that I feel that it would be rocky texture if I reached out, Stang's hair looks like real fire, the fishies look like cave fishies with super awesome blind powers, and Claude's hands? You don't get to really see the details on him cause he's a shadow but you can see his red hands! You didn't leave that detail out.
You can really tell how deep this cave goes and my eyes trail along from the opening to where Stang is. And with the walls, you can tell how wide it is too. You did such an awesome job. ;u;
