Wow, all you mini-castle builders are really pulling out all the stops. This is great. I particularly like the colors and the shapes -- it makes a nice, complete, interesting picture to look at. (I'm not sure if that makes sense; if I knew more about art I could probably use terms like "balance" and "composition".) For example, I really like how the flames on one roof sort of match the red tiling on the other roof. Similar colors, but radically effects for the actual building. And then all the green really balances it out.
Okay, I'll stop rambling about things about which I know nothing.
