I am never seen before this building...So I check real pics and compare with your MOC. It is hard build it in this scale, but in my opinion you did a good job
But my first idea was, that is waterfall from building. That somebody forgot close tap in bathroom
btw. sorry for bad english
there's something in that, with the tap, really
(as for your english, it is a lot better than my slowak, so don't you worry about that)
@ KLF:
Hotel spirit: No I think, without looking it up, it was maybe just inspired by Hundertwasser. That one should be easily built in microscale, just pile up little bricks in different colors, maybe use some kragle to keep them in place, and add a Hotel sign in the front
