Hey 88qba88,
Thank you for the input!
The apartment itself exists in real life and is an attempt to recreate that as realistically as possible, of course with changes to furniture and minor details. So for example the floor material is the same as the walls, because that's how the place was built. Concerning the wall material: I'm overall happy with it but I agree that it could be better and has some surface problems, even though it is intended to be a very rough element in the scene.
The tree outside is actually a model, you just don't see the geometry (only the shadow) because of the camera angle... I thought it added a nice touch of realism.
The Nighttime version: Lighting on the floor was intented to be a hint of moonlight (using corona sun), perhabs i went a bit overboard with it. It should be said that these 'mood' changes are made in post, in Corona LightMix and Photoshop respectively.
I do have some experience with LUT's, however i prefer to control the various sliders myself to get a more precise look.
I was very conflicted on wether or not i should use DOF in this scene. I had a plant in front of the camera for a while, but ended up cutting it for a cleaner look. Agree that it can be overused...
Thanks for the feedback will keep it in mind!
