A really good attempt, but the cellar needs some work. You made it too dark and straight.also, try adding some light blue ambient colors in the background, it will change the feel of the build.
Too straight? Isn't Semper Fidelis itself is....straight?Thanks for the answer, though.
What I was trying to say is that you only placed a few dark plates to make a cellar, the one in Battlefield's got way more details and everything.
