| sorry mate but i can see here just 8 triangles and a lot more quads plus you should you some kind of proper render like MI or FG they will bring you the crisp sahdows and realism to your scene but ofcourse will take a lot more time to render.plus the model is very low detail the house is empty you should build something inside something outside.
inside you could model some sofas bads tables thigs that are big and gets into eye first
outside you could model plants,a path to your swiming pool with other colour because one colour floor is a bit borring and if you have access to Vue you should import you scene into it and do outsanding enviroment.well good luck finishing your work.
