Hi! I'm not in the Berlin area at the moment, I'll be back on Monday the 17th, however, in case of being selected for the project, I will totally commit to it and finish it in one day, to have it ready on the 18th.
It seems like a fun thing to do, I don't think I know all the subways in the city so the idea actually excites me. The feeling is something similar to some photos that, sometimes when I travel I like to take, focused on street art.
I have a good camera and a lot of patience when dealing and walking through crowds of people.
Hoping to work with you !
