If you made the buildings in CD3 why didn't you keep the CD3 roof detail? Was it just to get the shapes so you could follow the tute?

I'd have thought the City Designer roof tops would look much nicer that the PS bevel.

The wall could use some towers and gate houses, as mentioned. Perhaps the water is a little too bright and saturated compared to the rest of the map.

Cheers. Thanks for sharing.
