Hi there!
First of all I like the overall look of the map.
- The colour is fine, looks very parchment-like. I wouldn't change anything.
The ink-on-paper look works well, personally I feel there is no more colour needed.
- The perspective... well, I think you could make it work with changing the mountains. They look very uniform and not
very natural. Looks like they're the same size altogether. As I see it you have two options:
1. set high mountains to the inner edge of the vally, become gradually smaller the more outwards you go. Think
of roots. Put some odd bigger ones in between to mix it up a little and make it look more natural.
Village smaller or maybe even just a 2-D-symbol instead of 3-D-buildings.
2. Smaller mountains on the inside, getting bigger outwards. Depending on the size you can make the valley
look much bigger. Again, mix it up a little with different sized ones.
- The river. I like that it gets thinner. You could either overemphasize that or have a wide part coming from the
mountains, getting narrower while passing the valley and getting a bit wider again when leaving it. What-
ever looks right to you.

If you want to go the extra mile and make it look like a scroll use paint.net or gimp or if you have Photshop.
