Thanks for the feedback,
The windows are modellled not textures, but perhaps I could make that clearer by putting some of the laundry in the windows from the original photos (you cant see it their but its on the original photo - no microscope :)). Maybe adding the windows in behind would help to.
I’m really only about 4 months or so into heavy dedicated blender learning, the background is a hdri , should I with that to put clouds in with photoshop? Or model them on blender, or some form of particle system ?
Will put a a full 3d view in, but it may look a bit wierd with none of the city around, I guess I can do an architect style render that you see on planning permits for skyscrapers with fake lawns etc.
Thanks again for the comments, its always useful to get someone else tips and opinions.
