I must say I like it, it's pretty detailed and still clean and neat. If you're aiming to a simple yet complete way of illustrating a regional geographic area, I think you're on a good road.
I think the mountains need a reworking, it's ok they're basic in this kind of map, but their shapes don't convince me, they seem to be more rushed compared to other features of the map.
I would also add a border (even the most simple one generally improves the overall work.) and maybe a legend and a title.
