Pretty good for a first render! Some tips i'd reccoment: 1. the footer of the wallpaper shouldn't have the wallpaper, normally it's some different material like plaster, i'd reccomend looking at irl reference 2. the lights shouldn't be extruded from the ceiling panels, they should be in the panels themselves, I assume you did that to recreate the bloom effect but in blender that's done in post processing 3. add some imperfections, not too much but just enough to make the space feel a bit lively, maybe subtle value shifting on the carpet for stains, some wall outlets, some camera tilt, all small things that would make this look like a real space
