If I didn't know any better, I'd say she's a match for the ATS Forums T-shirt promo babe. (All she'd have to do is put on some black Rayban sunglasses and a black T-shirt and take a photo with harsh lighting.)
Even if she isn't, she's still plenty cute. Because of that I'll give at least one attempt at drawing her from her reference pics. It'll likely show just how bad I've been out of practice at drawing with pencils.
