It's semi-intentional? :P I started out with more of a Flemish look in mind, but some of the buildings (mostly those with the long side facing the street and the roofs sloping towards it) reminded me of Germany as well, and I liked that so much I drew more of them. I've been to Freiburg in the Black Forest a couple of times -- it's such a lovely city! <3
I get a slightly German vibe from the town itself but I don't know if that is intentional or not. That probably helps for me though because German castles are my favourite and are the dominant aesthetic in my own little world.
