I'd like to add that it's the scene that makes it look unrealistic to me, not necessarily the building. A lot of the renders you see on here are new modern buildings placed in a desert, or a forest, etc. I don't really see any of those types of buildings in real life so it doesn't destroy the fantasy if they're placed in remote locations like I mentioned. In your case, that's a type of building I've seen before many times, and always in an urban setting. I see that render and I expect to see other buildings around it. It has roads, sidewalks, and even crosswalks suggest there's going to be some foot traffic, but... there is nothing around.
There's no context supporting that it's a real place, and that's what destroys the image in my mind. The setting so out of place for me.
