Nice job on this. You took the time to add some nice details like the shoes and clothes hanging which adds nicely to the scene. I’m curious if the roof shingles were an image texture or real geometry?
Either way, you created a nice and inviting space.
First of all, thanks for your positive feedback!
To your question: Yes, I actually modeled the shingles since using just an image texture looked flat and unrealistic (even with normal and dispalce map).
Looking good. I think you can improve the image by rotating the camera up until you can see the sky over the roof and partially hide the big rectangular tiles under the balcony. Then more overall contrast can help, easily doable with Ps/Gimp.
