I was going to colour this but I quite like it how it is. It's the inside of the Shed. It has a bit of a 'Tardis' effect in that there is a remarkable amount of stuff for a Shed of this size. Even a Giant's Shed.
The final character, not a very major role; Dolf Rickman the town (garden) mayor. My idea was to have him, being so small and physically diminished, become obsessed with the Giants in a Kaiser Wilhelm type way with the Potsdam Giants Regiments of Prussia. However he's becoming more of an after thought right now.
