very nice truth but you have some mistakes on the out side texture (the building texture) its not realistic with the hole image.
and it would be better if you put a wood texture to the railings and put it with normal maps so it gives you a nice look.
last thing make the light direction looks like the outside texture.
If you need textures or help just say it here and i will do my best for you 
anyways very nice idea and very nice design and nice blur reflections on the ground
