Now I can give you some feedback: I do like this type of maps and yours in particular, reminds me of my favourite cs_thunder. You've fixed the problem with palmtrees.wad but now some textures are missing:
This is a very strange gate that has two different halves:
I also find some corridors too bright. Adding shadows would improve the ambience.
Again, I really like your work and enjoy playing on it now. I hope that you improve the map by addressing the issues mentioned above. Good luck with further mapping!
