Here it is so far

Well, guys, sorry to say but I 'm not going to get this done by GDC, I will be there though if anyone wants to just hangout with a fellow artist ping me. But, I do really want to get this done, I'm in need of opinions/critique,  I decided to go with a cement/concrete wall texture. I thought the time period the bunker would possibly be made in, based on the radios, something between 1940s to 1960s. But, I could completely be wrong, what do you guys think?
