Hey thanks for kind words, I really appreciate that.
There is really nothing out of the box here. PBR materials tweaked to my taste, some trial and error with lights and most importantly adding lots and lots of props like books, flowers etc. That brings life to the image, I often look at lot of instagram "WAGS" pages to see what kind of images they post, beside erotic photos they tend to add a lot of "Im in Hotel XY" or "look what I got" photos. Where you can get a lot of "mood" inspirations. As for shaders there is really no magic, I don't really go further than what's this.
Last thing thanks to corona great VFB I literally do only 2 things in PS, I do some CameraRaw and add small chromatic aberration.
This interior was created for a football player with his girlfriends strong influence, they are a young couple so we had a chance to create a fairly modern design with some "bling".
