Medusa Picture

I've had a really tough day today and amid the flurry I left my sketchbook at home. So as I sat and ate dinner at work I absent mindedly picked up my organizer and began to doodle on the back of one of the pages.. over the course of my breaks and some spare time (I finished early tonight) I drew this. I like some of it, but hate some of it. I would like to hear your thoughts. HB mechanical pencil used. No reference.
