Tree Man Sketches

Okay so the most important part of being an artist is being able to create new images and ideas. I am always sketching and sometimes I get a winner, at least in my book. This is a pencil sketch of the Tree Man. I am working on him as a t-shirt design for Forest Walkers. I have spent enough time on this today I have to get back to the drawing board. Please tell me what you think, I honestly love to be critiqued.
