Hi Verena, once again, the extreme angle and point of view grabs me in this photo. Also, the technical stuff is well handled, the DOF just wide enough to keep the sign in focus, but not too wide either.
Good tonal range, too, and reaching out to a more subjective level, maybe if you decreased the brightness a bit, you would've been able to preserve a bit more details in the white wall. Not primarily necessary, and I also believe it would change the feel considerably (and not even for the better) but it it might just work locally. Hope you see what I mean.
