Really nice work, You have a great attention to detail in your modeling, and your texture choices are really strong. The only thing that needs more work is the lighting, which as it happens is the easiest thing to fix.
Firstly there seems to be way too much ambient light in the scene. This is especially apparent in the way the objects on the shelf like the stove, dishes and bowls seem to be floating in the air and have no real contact shadows with the surface they are sat on.
Like others have already mentioned the light from the window seems to be really burning out the wall, and the wall itself looks only paper thin where you would expect thick plastered stone like you have on the shelf.
The area under the main shelf, and the shelf by the window also seems way to dark for the scene. with that amount of bounce light it would easily be visible to the eye.
The best lighting advice I can give you is keep it simple. Start with a main directional light casting final gather rays or global illumination and build upon that. You will be really surprised at how few lights you need to add to complete a great looking shot.
Can’t wait to see more.
