I love your map!
If I'm allowed to give some suggestions (I am not a very experienced Cartographer):
Looks like you have different Layers for River/Road and multiply them each with Parchment-layer to make it look like drawn on parchment. Maybe save the map and try to combine River- and Road- Layer (Place Road on top). After reducing to one layer, you'll get rid of the river shining to your Roads when multiplied.
Some of your roads are drawn on mountain, or over sea.
Would be great to see bridges crossing the river (place them on Top in the same Layer as Road/River).
