Lounge Bar Isometric Room

First of all, thank you so much for sharing this class! I learnt so much about Blender and 3D modelling, your guidance has been invaluable. I'm looking forward to learning more!
As for my class project, I decided to expand on the piano room example by making a fancy, stylish lounge bar, with the piano stage as the centrepiece. I looked up references of lounge bars in order to create that relaxed but refined ambience that they're often known for. I included a bar to add some variation to the scene.
Any comments/critique are welcome!
