I like the first image, i like it a lot , the movement and blur of both subjects adds a sense of mystery. The circular compositions running through the image work really well. The brightness of the floor is something you might look at again if you are doing any more work on this image. Well done.
I’ve now decided that I like both of them – they each have a different feel.
I might also try to retake it this weekend with my SLR. It was taken in Brussels (incidentally, a much underrated city, with lots of fantastic Art Deco buildings).
