This certainly meets "minimalist" For me the lack of an interesting subject is what keeps me from being interested in looking at this picture for more than a couple of seconds. Maybe it you had some really wacky colors or if I couldn’t recognize what was making the shapes it would have been stronger for me.
kinda boring, the roofs seems to be pointing to something but you look up and there is nothing there... i think something as little as just having more sky in a portrait orientation would have helped.
