This is how I imagine most naga to be put together; as if their body begins merging into a snake form from the thighs down, leaving the rump and crotch in place. I think it adds a bit of extra, sexy curvature to the body, as well as some sexual options that isn't just pure bestial snake sex stuff.

I'd love to see this character drawn from behind, to see how her body is put together from that angle.
