Your map is quite nice! Love the color scheme and it appears you've got the 'aging' effects pretty much nailed down.
One idea to consider is to to possible have small 'hand written translations' of the lettering (which appears to be a Tolkien font) so that folks can see what they represent. *shrugs*
My only little nit-pick is that I find the compass rose a little large, but that's more of personal preference thing.
If you feel the map is finished, then there is a 'Finished Maps' forum for you to post it in if you'd like.
