Wow, Sow_entombed looks impressive... especially those camel & horse models. Did you make them yourself? But also the rest of the map... great stuff! Now if only I knew what "sow" stands for...? (Excuse my ignorance)
Just a few tiny things: In the 2nd screen, that long wall looks a bit "cut off" on top, and in the 5th screen, that building with the round window / ornament looks too two-dimensional... it's quite visible that it's just a wall and nothing behind. However, I doubt if these details will be noticeable in game.
Btw, I like the name "entombed", hehe...
Sow_hangar - is the outside area finished? It could use some details to spice it up a little. The village, however, looks pretty damn awesome! What's with that cable sprite (is it a sprite?) in the 2nd screenie... it looks like a section is cut off & missing? Just a minor glitch, though.
And what's that sniper rifle? That must be one of the ugliest weapon models I have ever seen. It looks totally unskinned, and the scope mount is blockier than a Borg spaceship...
Well, the khefren screenie is really too dark to reveal much...

but if it's up to the standard of the other two, it must be good!
