Played it this Saturday Gameday, and it's a very very strong map, I can tell it's seen some polish! The egypt style is executed very well here, indeed. There were a few things that jumped out at me as I was playing so I went through just now and took a few screenshots.
This is probably the biggest critique I have (and ties into the previous suggestions of improving the lighting). Basically, mostly everywhere you have these red overlays, they're in no way eye-catching. Signs should grab your attention, not something you search for. I think the reddish/orange tones in your lighting drowns these out. This screenshot shows it best, I think (can you find all three Red A signs?), and it's prevalent almost all over the map where the red signs are.
Just a small nitpick, but to me, this seems like torchiere overkill. It's pretty distracting and looks a bit cluttered, though this may be just my opinion.
This is a lighting issue as well as a signing one. In the spawn, you have a sign over C, but nothing to indicate the door on the right can be used too. Without the light leaking on the floor, I would have in no way be drawn to it as an available route.
I had a few issues with this particular area during Gameday, namely that it's easy to get stuck underneath, and rather difficult to get out and onto the pillar correctly. It may be a design choice to make it something to work for, but I wanted to bring it up nontheless.
Bottom line, it's a fantastic map, plays very well, and hits the egypt theme perfectly. I look forward to seeing the final result!
