Not bad, I've seen worse from newcomers. I'm telling you though, your best bet is to get working at a shop and start small. Get a real pro to take you under their wing and show you who things work. I've known artists that just do their own thing for years and never really get better, and I've known artist who have been doing it for less then 5 years and working with some amazing artists and it really rubs off. Get in at a shop and put in hours of just cleaning, watching, drawing, whatever. It'll pay off in the long run, I guarantee it.
