Fantastic, high quality render!!! Technically I can't put my finger on anything that is wrong with the scene. The modeling / materials / lighting are all very well crafted. However, i think the scene does lack a sense of composition in the frame. Not necessarily the objects and furniture themselves, but the camera angle. I find my eye drawn to the middle of the shot and all the interesting pieces are small and farther back in frame. There needs something to draw the eye diagonally across the view and through the depth of the image. We see just the edge of the window on the left that is pouring in this beautiful light, maybe rotating to see some of that would give more dynamic to the shot.
Personally I love the small windows and the big red wall, but I would loose the red on the wall to the right with the fireplace / wood logs. Maybe some material change in there would help break it up? Just a personal suggestion.
All in all excellent craft, look forward to seeing more
