Work Flow
This is just a quick work flow tutorial. Here’s how i normally setup my scene:
1. Get all the references: Design, lighting mood and etc.
2. Start on modelling the scene, put on material, set up the lighting and camera.
3. Do small resolution render test to get it right, 500 pixel is good enough to see the details. You can also pick one spot and do a blow-up render.
After few attempts, i got this image:
As you can see, the floor is too dark and looks cold. So I change the floor mat, smooth the chair and adjust the lighting/colour mapping.
and finally the PS part. PS is a powerful tool to help you enhance your image. In this one, I use chromatic abberation and put some yellow and green. 
I hope this could be of some help to you. After all, the pure render is the most important part. Good luck!

This one is a quick lighting test i did last night. Scene was taken from a magazine scan which is quite noisy. **that’s why my image got so many noise**
