white closet

Description:

My attempt to create an appealing photorealistic picture of a clostet. There two pictures added. The frist one (The square one) is mine. I found the second one on the internet. This one has the target quality I would like to reach.

I have the following questions: 1. There is a distinct difference in shadows between my picture and the target. What can I do to improve the lightfall and shadows? 2. The floor in the target has some form of depth of Field. How can I recreate this in Blender? (this specific effect as shown in the target) 3. The floor in the target is very uneven. How to do this in Blender?

The target is form: https://nl.pinterest.com/pin/54254370494571446/ It is an Ikea closet (Brusali)

The floor is based on textures from: Poliigon
