hi alavro,
i had sent a reply as soon as i got the pics... the shots were very nice...
i am NOT a mapper

If you see my maps have just the same building blocks e.g. Simple straight walls... lol
I am currently working on integerating CShop4 scene node via a custom scene node which uses
a) entity properties
b) supports shaders

c) allows for waterblocks
d) Volumetric Fog (don't hold your breath... this one is going to take a looooooooooong time).
e) Shadow Volumes for map geometry.
f) Vis Group based culling
g) Trigger zones (Ghost blocks)
e) Movable Map Geometry (like Fans, Doors, Elevators etc.)
(Actually I created a much simpler format (same as CShop but less bulky called LAMP format)
Josh (the author of CShop) sent me the file format for CShop5 and sample files... so i am trying to support Cshop5 when it is released.
