As per Phils suggestion I've gone back and had a slight think about the visual direction of my piece. I'm currently in a mindset where I'm just subtracting real world textures and replacing them with arbitrary texures of my own. It works, but needs resolving to a greater extent. The idea of a non-cg aethetic needs to embraced further and to effect the entire style and language of the animation. Phil recommended Charley Harper - famous for his highly stylized depictions of birds and wildlife.
I'll follow up with Mary Blair who produced the concept art for many Disney films.
