Smexy! :p

I like this. A few things though. Would have like a little more face, such as her nose and a more defined corner of her mouth. Also, I can tell she's wrapped in silk. But I'm unsure, other than an almost suggestive scene as to why it's mature only. It's not even mildly soft-core. And if she's hiding from view, more blushing in her cheeks. The eyebrows need to be a bit more defined as well. The coloring is really good. Erase all your extra marks here at the underarm. Good work on this piece. You have good talent. :3
