Yup great WMD (weapon of mass destruction) here, sometimes when the neighbors turn the country music up real loud, well (oops thats another story). This is a great view and the expression on the models face (and clarity) sets this whole shot up nicely. Could have worked in the unusual viewpoint challenge as well. Good dof and nothing distracting in the background. Good Job.
I like unusual perspectives but I don't think this one is working. I like the expression on her face and the simple background.
I play a few instruments, including guitar, and while I might call it a hobby, a passion, a neccessity....I wouldn't call it a habit. A habit implies an unconscious act or gesture.
Cute model, nice lighting. Good composition taken from unusual angle. The halo around the guitar is a bit distracting. Finally a dark background would probably work a bit better.
