Alright, downloaded and played. Review Time.
The Good: Arena style maps are always a frag-filled blast. The custom music, while it doesn't compliment the theme, was interesting and a refreshing change from razor-ub.
The "Areas for improvement": To be frank, Architecture wasn't really a wow or memorable. I understand it's an arena map so it should remain simplistic and symmetrical, but you can still work within those constraints and create a map that players will keep on Dming in due to some feature which struck them as unique. Tips? Oh I dunno... A giant pharoah looking down upon you in the skybox? A "Nile" river cutting through the pyramid? Booby traps and hidden undeground tombs (some 1337 Indiana Jones rip-off)? And so on, and so forth. Aside from that, a few other things I noted were missing trims, gas lamps (torches emmiting orange flickering lights would've enhanced the theme imo), and the flat "Egyptian" architecture. Look at some pictures of actual Obelisks and Pyramids/Temples and mimic them in your brushwork. The skybox (for a map which is to be fought in mostly outdoors) is ..eh. Slow-Panning skies and a contrast of cold and hot lighting (Purple/blue and Orange/yellow) looks nice. One more thing, the outer area, namely the flat stone wall perimeter, really wasnt too convincing. If the pyramid were set on an island it would've looked great imo.
I'm ranting here. Lemme calm down.
Ok, I'm good.
Anyhow, being a critic is easy. Map making is tiresome and often agitating.
You made the map, and it was as good an attempt as any other novice mapper.
Look at some of the pro's maps and mimic their brushwork to understand why they made certain areas on way or another.

Check those out.
After awhile of stealing, your own style will emerge.
Au revior, Air.
...I'll build a new version of this map with more "wow" included.
