We need scales on every map. This may be one of my pet peeves. A person can walk/hike about 20-25 miles in a day. I'm not totally sure, but I think your map is something like 300 miles across. So you would expect a 12 day journey to cross your map. Using a scale ( |----------| 50 miles ) can also help you understand how many settlements should be on your map, how wide your roads and rivers should be, and how large the map symbols might be scaled to.
Anyway, this is an amazing map. It just needs a scale, IMO.
