This is just my little opinion, sorry for critisizing.
Floor testure is too boring and rough. Viewer was confused whether it was plywood of carpet..
No reflection on the table.
No shading is found.
Flaw found on revolving spine, set the it higher.
There should be bump on the hanging cloth and cushion.
Mapping of the lady poster was projected plainly, so you will see stretched text under the poster.
And the most vital is the spot light, a spot light emphasize the main theme, but in your rendering it seems too many focus point to mention. There is also a room for improvement of camera angle, try focus on the apple with a lower location of camera, then apply DOF which out-focus and dim-lighted background.
