This is such a beautiful picture! It helps that I really like artwork of dinosaurs. They were something that I was really into as a kid. I guess you can never really tell what they looked like in the flesh. This is as accurate as any other drawing. The girl's nicely drawn too.
The whole thing looks like it was done on watercolor. Then again, a lot of submissions are. I think that's a pretty accurately sized T-rex. The vines in the background are a nice touch too. I couldn't help but think they spell something out.
