I just finished painting up a windmill by the Croatian vendor
Tabletop World. What a great little kit! I love Tabletop World's work... details are deep and exaggerated, making painting fun and the final result full of character without getting too cartoony.
Assembly was simple (the arms of the windmill are separate pieces that must be glued into the roof assembly, but that's it) and there was virtually no mold lines or bubbles to deal with.
A coat of black spray primer, lots of shades gray, brown, blue and tan for the stone, and various washes, pigments and drybrushing to pull out details and weather it and it was done.
Tabletop World is running a Christmas special currently, and while shipping does take a while their stuff seems worth the wait.
