Woodland Backgrounds

This is some collab work I've been doing for Mike's film. He's given me rough layouts to explain where everything goes and he's just letting me do my own thing. Cheers maaayte :D Must not mess it up! He wants a Yogi Bear background style throughout so I've been looking at loads of references as most of it is done traditional so I have to make my own take on it in Photoshop. I been making my own brushes to create texture so I think I'm on the right lines now to create the style needed.
