Where is the feedback people!!!!
I agree with Krall on the Egypt flag - if the country is modern Pharaonic Egypt, I'd expect something different from "various ancient Egypt symbols on a flag". What's the culture like today? I presume everyone isn't riding around in chariots and so forth. How has the country evolved? Has Egypt gone through any non-pharaonic periods? I think it's a pretty neat flag, but it's hard to imagine how such a flag would come about historically.
IMO, the eye is a stronger symbol of the pharaohs than the sphinxes. If you simplify it, I'd keep the eye. If you want to give it a "modern" feel, you could even make a more geometrical Eye of Horus. Here I'm thinking of Germany's modern coat of arms, in which the eagle has a very different look from the one on the traditional heraldic coat of arms.
