Hey, this is my first big project that I’ve worked on, so it took me a while but I learned a lot and I’m proud of the results. Please, feel free to give any and all helpful critique, specifically on how to make it more realistic. I’m all ears!

You render looks really well, as far as I can tell your models look very good. The only thing I would adjust is your lighting and textures if you want to match the original image. The wood floor has a blurry reflection and the room is a little brighter. The cabinet on the left looks a little bit wider than the original as well.
A side by side comparison makes it easier to spot the differences in the floor and lighting.
Thanks for pointing those things out. Setting up lights was a real pain for this project as I’m not too well versed with the ins and outs of lighting. Looks like it’s time to do some research on the topic!
