Last year I worked with Rhys on his film 'Sporkbender'. He drew all the backgrounds and I coloured them and added textures and stuff. You can see more of his work on his blog which is HERE!
Here are some of the backgrounds. I can't seem to find them all (my hard drive needs a serious clean out...) but if you want to see more, go look at Rhys' blog.
You should go watch 'Sporkbender', too. It's here!
