A quick update on where this is heading!
I'll take Simon's and Richard's and work more on the textures of the hospital walls Rich pointed me amazing examples of old and faded wall textures that I will refer to when redoing my textures, after all was really late yesterday to do something worth in my scene :P. So now with some fresh memory and good reference pictures I will start to paint the wall once again. I would say a bit of DIY won't hurt anybody :).
As the world outside never stops in the Maya world happens the same, so I took a couple of hours in the morning to do some more modeling, some small details that will give a more realistic look to the scene.
I have created a light switch and a door, which in similarity with my concept will be placed next to the door frame but not in place.
On the door model, I will be adding a doorknob on the right of the door model.
and now going back to the Maya World!!!
