This really doesn't look good but as it is a WIP, I will encourage you to improve it:
-What kind of DoF are you using? From Corona or done in post?
-the glass model doesn't look very good and it is placed very close to the camera so all its flaws are visible
-same applies to the bottle - ugly blurred textures
-windows have sharp edges - they should be blurred by DoF, too!
-the background bitmap is in poor resolution
-think about composition, why are the glass and bottle cut?
