Sci-fi room concept Art - Perspective view

I have been trying to practice my perspective drawing skills as i will probably not be able to create the room in 3ds max and unreal due to computer issues. So instead i am trying to give a drawn representation of what it should look like, i'm pretty terrible at concept art so this has been a big challenge for me to do. I started by mapping out the objects in the room using reference imagery of my old concept art work i created. I then followed the level map i made to find out where each item goes and went from there.




I then moved onto some basic shading, its in relation to no light source as i have just been shading areas that i think would make the object look better.
