Very clean line work, though your title confuses me. I'm listening to Chopin's piece right now and honestly can't see how it fits this image. What this image is conveying to me is a normal scene on an average day where a teenager is watching some show on her PC. Which, by the way, I always find mildly interesting, like peering into a scene of someone's life, I could see myself in the exact same position. However, Chopin's piece for me, is slow, relaxing and soothing, this image isn't exactly that. Though the character does seem kind of relaxed, actually, she seems rather bored or apathetic, I suppose the scene as a whole could be viewed as relaxed though.
Regardless, its a nice piece either way, and thank you for showing me Op.37, I was listening to another Nocturne (can't remember which Op., something from Vol. 1) earlier today but I think I like this one better.
