Nice work.
I think people may be thrown off by "figurative" which usually implies something different from "relating to the human figure." "Figuration" is usually used in literary and art criticism to refer to the use of "rhetorical figures" in the case of writing, or to various kinds of substitution of an image for another image or for an idea. Metaphors, both visual and literary, would be examples of "figuration" in this sense. "Figurative" meaning would be the opposite of "literal" meaning.
I think these figure studies are indeed figurative, and closed-minded people are sometimes afraid of creative work that isn't absolutely literal, so it is probably a good idea to warn them before entering your website, as you do, that they might find some things that don't have an obvious meaning there.
