Thanks all. I have taken all the feedback, and made various improvements. The Emyn Uial got a new texture to fit it's climate. Ithilien is loosened up, more paths and less dense forest, more sparse. I finished the last of the major rivers, adding the Gondor rivers, the Gladden and the Forest River.
Here is some previews of the work on the whole map. Harad, Rhun, Gondor and Mordor have no polish, and the Blue and Grey Mountains need to be redone.

On some maps, including this one: http://www.glyphweb.com/arda/maps/ithilien.gif, Minas Morgul is north-east of Osgiliath. In most maps though, its either level or between the two extremes. I'll have to find a balance. It does make it longer to march to Osgiliath though, making it a bit easier on the Gondor player
