First, I've began applying the textures to the big castle at the very peak of the village and the terrain. I wanted to wait with the smaller buildings as they mostly populate the entire scene. The goal was to first set down the base textures for the ground, see what works, move on to the castle and then texture the remaining buildings.
I wanted to spend a bit more time testing out what texture and color combinations work best, but I felt that if I spend even more time on this phase, I might run out of time. I'm delighted enough to move on and finish texturing the rest of the houses and animate one or two videos.
