Testing Room/Lab Sketch I

This is a sketch of the lab that I created the other day. My team suggested to include sleeping chambers/pods. I will experiment with other ideas  today and tomorrow also - I will try to at least create one decent image that is some what complete. I haven't used any reference for this or the other concepts that I have created so far, but I really need to start doing that.

We are still trying to make the interior environment subtle and muted in terms of colour pallet so that this aspect can contrast with the exterior environment - to give the idea that the inside is dangerous and  the outside is somewhat peaceful. I want the variance of mood from the outside environment to the inside to have an impact on the player. Originally  I wanted the whole map to be subtle and only when the player escapes the environment the mood changes but the latter can also work if done correctly. Michael wants for the outside environment to look similar to avatar all colourful and staff but I am trying as much as I can to make it not too cheesy and not too colourful.
