This looks like bloodrayne 1 , though that game had more displacement than you have done here. It is another depressing map , by that i mean the theme is depressing but that is the idea of zmod.
The buildings screem into my eye because they are poorly made, really quickly block by block. And alot of walls are just plain blocks. Where have you seen cliffs be so straight?
The fps is incredibly low, you we're the only person on the server and you had 87 fps, now think about a full unlimited ammo server where everybody has a smg and they all shoot, the fps will be around 5-10.
Oh and shouldn't that bridge have ropes?
The fog is good because it fits the theme, and so are the trees with the leaves falling off. It all goes by the map's theme and that keeps it in balance.
Oh and for fps , try optimizing :)
