How to do Realistic or between

[Conna3005]

Greetings.

I had a little Exercise on Lighting and Interiors/Exteriors.

This is the Way how i done the Setup. I would like to have more Realistic.

I am using two Area Lights, Octane HDRI and Sun Object for Interior. I got a better Result than before, but it could be a little better.

I am using a Noise Shader for the Walls. The Original Cinema Noise. I m not using the small from Octane.

I could use a little Advice on the Setup. I could use the Collor Temperatur, but i must combine Sun Temperatur with Sky Temperature.
That means Blue with Yellow. I am not Experienced with that Setup and could use some Advises.

At least it looks far better than before.
