Day 24:

"It's not easy being green.  Work only with green-coloured materials today.  Try working on a green surface for a real challenge"

Green in a nature theme should be really easy but I just couldn't seem to come up with anything creative today.  So I found a bright green piece of paper and a green Sharpie.  No real inspiration seemed to come so I doodled some Kerropi inspired frogs.
