Art? Doodles?

I need to start drawing again, it's the only thing that makes me truly content. I always have a weird issue about labeling my work. Is it art? Or just doodles? I feel like I'm not at the point where I would consider myself good enough to be an artist, I don't know any proper techniques and haven't even taken an art class. I'm hoping to take some classes this summer and move away from simple doodling. In the meantime here are some of my most recent "doodles."
