B&W makes it hard to tell if this is neon; just doesn't work as well as color for this challenge, IMO. The model is not quite well enough lit to be sure what she's doing ... looks like there is a dark thing coming out of her mouth, too, and I can't quite make out what it is.
I think I liked this better at first glance before I saw the face in the corner sipping out of the glass. I like the simplicity. It looks like the border is part of the continuous line. Maybe if the face wasn't looking straight on?
