I hope this is okay. I tried to do shading with the colours I had, but had to add 2 extra colours in order to do it (per the rules). I made a nymph/faerie gal using the dingy jungle palette :)
This actually interests me, so I'll see if I can work on one.
I would enjoy trying to do something out of the box (so, different from the previous flag skins iIve done that was just a hoodie in the colour of the flag)... Could you give me a random country flag?
