Dream Sequence Light Tests

With animation already starting and some minor tweaks to do in either the rig or the environment, I had some time to explore lighting,therefore I have began doing some light tests on the dream environment. this environment is still in choosing stages.
Firstly, we were thinking of having a total blank space, then adding the environment with a spotlight focusing on the character, and also we thought of having the environment, but with no textures in it.

Here are some light tests I have done with the main different ideas:

BLANK Space

 Render With Default Light Set up

Render With Default Light Set up + Ambient Light 0.4

Render With Default Light Set up + Ambient Light (Range)

 Render With Default Light Set up + Ambient Light 0.5

Night Time With Spotlight
