I think that the reason that it looks boring is because past the building,(which is cool), there isn't really anything to look at. It doesn't make sense that there's a man rowing to or from it in a boat because the building looks uninhabited, and such a large, intricate building would have things in the windows, people going about their buisness, and other such things. He could be looking at it out of intrest in an old, abandond structure, but everything seems to be in good repair and the colors look new and bright like they were freshly painted. The problem, as I see it, is that it looks as though it was just put there too look at and not touch, like a room from a magazine, which is nice and crisp but lacks anything human to relate to and gets boring after 5 seconds.
Sorry, I got really wordy there, I do like the picture, especially the achitecture.
