You created a very interesting range of tones here. It almost looks like selective desaturation with the grey of the building and the neutral coloring of the vehicles parked along the street. I do feel that the large, colored flower pot is placed too much in the center of the image. With its coloring and the lack of colors elsewhere, the eye is drawn and held there, not giving the voter ample opportunity to explore the image. I think that you met the spirit of the challenge well, but the image could use a bit more interest.
i'm trying to figure out if every scene has the potential as an amazing image, and it just depends on how you look at it. I'm very curious about what i'm seeing reflected in the window, as in the least, it's duotoneness is very eye catching to me.
I don’t have much knowledge on street photography but my thoughts on you shot are as follows: This shot needs the selective saturation to make it interesting as there is nothing to really focus on in the shot and I find the pole annoying. Sorry.
