I'm back on it

So, I've had a couple of art test's and some contract. I had to put this piece on hold but I'm back. I decided to redo the metal texture, it was to shiny and the roughness map had low contrast.

Here is the new one:

The first texture:

Let me know what you think.

Still going

As I stated in my last post, I'm continuing the progress on the bunker. However, I want to say that GDC was great, I went to a bunch of sessions, some parties (polycount meetup was the first on my list), and met some great people. Definitely something I will thing about saving up for in the future. I didn't do much work that week, right after that I had work on some contract work. But now that I have the time I'm back on to the bunker.

Here are the tile-able materials I work on so far. Critique definitely wanted.

Decided to add some flats to this post. I didn't use Substance designer because I'm a poor artist atm.

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?
