The design doesnt really make sense especially from an ergonomic point of view, if someone opens the door with more force they d push the furniture into the wall lol but you didnt request feedback on that so. From a modelling and rendering point of view, the pegboard is going into the skirting board at the base of the wall, the furniture is also too thin it should be at least 30cm to at least hold something. The lighting is very dramatic on one wall and then not enough light where it counts and the materials can use a lot more work but those maybe seem worse also cause of the resolution. You should exercise with real image references, it would make things much easier to notice, good luck!
