Very cool. However, the "teen girl" bit threw me off. She looks like she's in her late twenties - early thirties, what with the tall and fully developed figure and the angular face, which is a common aging trick. Very lovely drawing though!
Wow this is a beautiful lineart, I love the weight of the lines and how clean the overall image is. Also, her hair appears so glossy and you drew her in such a suggestive way, look at those sultry eyes and lips! This would look fantastic colored but either way, man this look really nice!
