I was just browsing through thoose pics once again and.. I noticed a proof that Fairywintah is using doodad/terrain palette..
See that little red area? It's a green square that only appears when using Terrain/Doodad palette.
Otherwise if he was using RAW, it would be a shaded pic of the part he chosed.
Nothing bad meant, but I'd strongly advice you to use RAW all the time.
