The Light Setting in the Room

 At the beginning the light I setted, is too general, but no sad feeling as my concept.

I found two reference of the light I was looking for.

Therefore, I made a few changes of the lights

1) reduce the Dom light exposure.

2) made the direct light from the window. The directlight temprature set cold. 

3) in order to emphasize Jinni was a good student, I added three spots lights to light the medals and certificates up on the bookshelf.

4) I add an area light to light the general bookshelf and desk

5) I add another area light to light Jinni up, but not effect any of the other object in the scene

The result looked like below:

The whole scene was improved but still not as good as the reference. I had to work on the colour of the lights.

1) I changed the Dom light colour into a dark navy

2) add a little warm for the spots lights which light the medals and certificate

3) add a little warm colour for the area light of Jinni

Then the whole scene looked much nicer:

However, as Jinni's area light's was light from the camera, Jinni looked a little flat. Therefore, I changed the area light from the camera side to the front of Jinni's face side. The Jinni looked more 3 dimensional. You could see the shadow was nicely fell under Jinni's chew.

So, here was the final look with all the lighting changes:

Here is original concept:
