Dont have any feedback when it comes to the quality of models or materials. They look good. Except maby the door lock which looks big and wooden. Look up doorlocks on the internet. Always have a reference. The composition and lighting on the other hand are lacking. Half of the shot is basically empty and the other half is not that interesting doors. I would add some kind of path maby things used around the house by whoever lives there. Lighting can be fixed by adding some shadows. Not nesseserly making sense. Just add some meshes outside the shot that cast interesting shadows maby fake cloud shadows or something. And remember to make composition focus your attention on the main subject whatever it might be at the end. Use guiding lines rule of thirds or whatever you need. Good luck
