Making glass building more photoreal

Hello, I am working on some tropical environment project. As you can see there is a glass hotel in here which doesn’t blend very well with the environment. And when I say that it doesn’t blend very well, I mean that it doesn’t look very photo-real. It’s just off. I want it to be glass building, but yet when I add some smudges on glass it looks bad.

So how can I improve this building so that it keeps the same basis (glass building) but yet that it doesn’t cause people to say “building doesn’t look photo-real”?
