I think the statues are right between silhouette and properly exposed - which would make them underexposed. . If that's what you were trying to get at, then you succeeded, but I would prefer the statues to choose one side or the other...
^^ Agreed. I'd rather see more detail in the statues. So, yes, too dark. Why'd you go with 100 ISO? Just curious, I'm still learning so if there's a reason I'd love to know.
