Well definitely a solid beginning on digital. One of the areas I feel needs a little work is the North Eastern mountains. They seem faded for some reason. Comparing them to the southwest mountains really shows what I mean. Normally, I'd make sure the colors beneath the mountains don't bleed across the lineart so much. Or add some shading and highlighting to make the mountains pop more. But I'd say fiddle around a bit and see if there is something that works for you.

((Just a side note seeing that you hand drew the map also. You can give scanning your hand drawn map and coloring it digitally if you want. That is how I started my digital mapping journey. Also, I hand drew a lot of assets and then scanned them and worked them over digitally to give several cool assets to use on my maps.))
Still, good solid start. I'd say to start teaching yourself to use shading and highlighting. It really helps with maps.
Good luck!
