This is the background I rendered for my squirrels. Heavy on the classical animation style.
Only, I made a critical error with my layers, and you can see strange squirrel-shaped artefacts that look a bit like shadows. That, and some of the colour elements are misplaced.
Today I was too busy to make the fixes, and to be honest, I don't know exactly how I will accomplish the fixes without reverting a couple hours' of labour. I will try Photoshop's powerful repair tools and hope they work.
