The floor is just too busy as it is, I'm having trouble pinpointing the exact issue but I find it visually distracting.
I did an edit to try to work out what exactly was bugging me:

or a thicker doorframe, which looks better I think

* Changed shading on door p. much entirely: same general pattern is intact but I changed it from indentations to beveled squares, referencing my own door

Not sure what you were aiming for with the doorknob so I just made it round.
* Made planks in floor larger, added another shade to them: I think this scale for the planks just fits the other objects better, and it's less visually distracting
* Added quick shadows just to see how they'd look - I know you haven't added them in yet, no rush!
* Added frame around door: doors do have a frame, and it helps it feel more like part of the scene instead of a decal on the wall. You could do a smaller wooden frame around the door (matching the door colors) if you wanted something more easily reusable with different walls, depending on how you want to handle the frame.
* Tweaked colors in wardrobe to fit in better with door since they're both wood, not all that necessary but you've got a weird greyish-brown shade in there that doesn't seem to serve much purpose so I got rid of it
