I have started learning Blender a year ago in my spare time, would be interested in honest criticism to learn more.
Thanks
The image looks good. Lightning and color looks good. I think, it is rendered in cycles. I don’t have much experience with cycles, still using blender internal.
The glass plane on the right side of the stairs is intersecting with the stairs, it’s obvious on the second step. I think you should look at reference images, how a glass railing like this is connected to a stair. Oh, after a short image search on google I found rthe reference image for this render, the Radisson in Glasgow. The glass plane is actually fitted directly on the stairs.
So I would change the glass plane so it isn’t visible at the front of the second step. The wood texture on the back wall is too big, I think. The marble floor should be reflective.
