very nice map you got going there. everything is clean and put together well. the texture choices are sharp and the theme is executed nicely. that ankh shaped mirror is really cool the placement makes me think there is another path there instead of a mirror. excellent sky color too.
here go my suggestions:
-the map fits sort of an ancient ruins theme, however it is in pristine condition, i'd like to see some broken tiles, pillars, supports, exposed dirt/sand etc scattered around a bit.
-also i was thinking you should add some 6-12 unit thick circular details like handrails or something to that effect, just to bring some of the large architecture down to scale with the models sizes. right now i just feel a bit too small in that map in relation to some architecture.
-i feel the blue lighting color is too strong, try desaturating and darkening it a bit and see how it looks.
-maybe a nice mapobject or two from here
