I have now finished the windmill upon which I was experimenting. I am quite pleased with the results, though I imagine that the quality of the piece would make it hard to get a bad finish. This tabletop world terrain is simply mind-blowing.
Anyway, after a bit more painting, and dipping, and pinning and gluing, I had the windmill 'finished' to the point of requiring only some touchups and a coat of matte varnish.
That would work well in a pinch, no? While it looks nice, I found the metal was too shiny for something left out in the elements, and the stones needed some weathering and differentiation of colours. A healthy number of stones were given a wash with a mix of brown and red ink. The metal was given a similar was to simulate oxidation. I then washed the bottom bit of the windmill with green and brown to simulate moss and moisture growing up from the ground. Lastly, a drybrush of the stones to bring out the detail, as well as the blue shingles, and a few touchups here and there give us the finished product. It was sealed with a spray of Testors dullcote.
Lastly, we shall give a parting shot with the wizard of the tower (should we just call him the miller or something?) with a landsnkecht mercenary.
