i am aimed to create a photorealistic indoor scene, which I can use for furniture rendering.
My goal is to create a flat in the style of art nouveau combined with state-of-art-elements.
Everything is entirely done in Blender. No Postproduction at this early stage. Of course the scene is still missing some furniture and some parts are waiting for a proper shader.
I highly appreciate every single comment on improving the lighting, shading etc.
Welcome to the forum. The project seems to be coming along very nicely. Obviously it will need additional samples to clear out some of the noise. One area I would suggest a second look would be the wood floor, specifically the width of the planks, they look to be scaled too large in my opinion. A nit picky thing would be you might want to adjust the Y rotation of your camera slightly.
I think that the radiator is way too big. Also if it is Art nouveau style perhaps the radiator should be hidden. It was not very common to have it exposed like on your render…
I would also choose different floor - maybe some parquettes…
Thank you harleynut, BAGraphics and maraCZ for your fast replies. I will take every single tip to account and use it to optimize the renders. As a next step I try to improve the floor and optimizing the quality of the renders, while keeping the rendertimes acceptable. Thank you also for the advice about the radiator. I am either going to remove it or hide it behind some wooden cover panel.
