Thanks for your kind words!
Concerning the domes: most of them are are made from polystyrene balls. I just cut them half. With stripes from cardboard the domes become more structure. The top of the dome is made from a hirstart form: Turret Mold #61 (the mold includes a complete domed roof, which I used as an alternative to the polystyrene balls. But the balls are cheaper, easier to made in my opinion and they weigh much less). Then everything is sprayed with spray paint in a bronze colour tone. The last step is to paint the cardboard stripes and the top in Citadel Nihilakh Oxide. And of course to add snow and icicles.
