I photographed a dream I had.

A very nice and effective HDR. The thing about high dynamic range photography is that it is meant to be used with a certain purpose, to achieve a level of realism in your photo that you couldn't get otherwise. This particular shot does that very well without dropping off the cliff of surrealism that often looks so misplaced in this genre.
I remember visiting the Old Town in Stockholm myself a few times and this is indeed what I remember and liked about the place. That means the photo is not only realistic, but also characteristic. Despite that, however, I do think that as an artistic photo, you could try something a little more daring. Old Town is great for shooting old buildings and streets, but to the viewer, this gets boring pretty soon. So try to get an interesting angle on the things you shoot or experiment with depth. Combined with your eye for HDR, I think it'll turn out nicely.
