Pros: This map is really, really good dude. You have put a lot detail into this and the turnout is just amazing. First off, let me say, that the overall look and feel to this map is incredibly immerse. It really feels like you are in a part of a ruined city. The use of sounds and the detail in brush work makes it realistic. You did a good job of optimizing and the map runs at a good frame rate on high settings, and yet you didn't sacrifice any detail, excellent job. I don't think there is any more you can add to make it better, because it is very close to perfect. Every little detail you added goes a long way. Good job :)
Cons: Well, here are a few minor things that you might change in the next version
-There were a few texture mis-alignments on the brown brick when you are walking into the basement.
- I saw a few light props that were in a weird place(not aligned to the wall)
- The ground in the bottom level should be turned into a displacement to give it more detail.
Improvements: Fix the minor bugs, and maybe take my suggestion about the floor in the basement.
Notes: Let me know if you have any questions/comments about my assessment.
