Concept Art Trial 1

I am now thinking (now that I have the basic story plot) to work on building up some concept art and colour layout for the short film Brother Doctor (working title)

Here is a fast video of my first try at colour concepts in the Staff Room

With this, I pay with two main colours. Red and Blue. Why? They are very different on the colour wheel and contrast a lot with each other. This means, it gives some interesting objects/points of interest in the room, instead of it being just blue. The purple is the shadow in the room (I will play with different shading colours/ideas)

These are my try 2 and 3 at the colour concepts. I think having it blue with a hint of yellow in the light is a good idea. The shadow stands out a lot more due to it and the doctors face cannot be seen at all. it is a cool effect
