I agree with AcidAlex.
I think it's pretty damn good. You definitely have a style, though, of the attractive ladies you paint. They're all heavy - not fat, particularly, just fleshier. I like that occasionally, but it's good to mix up body types. Oh, and species. But you do humans too.
Maybe it's becomes I'm sexually fucked up, but this obedient pose she has is really hot. Like, really hot. Artistically, just be a little more detailed with the shading.
