Wow, that's pretty impressive for a first map! I like that you distinguish between political and cultural borders.
At first glance (on my smartphone right before sleeping and being very tired) your maps look solid. Good choice of colours, nice mountains... I'd like to see a merged version of geography and political/cultural maps, since geography is a big influence on those.
Also, of course, officially welcome on the forums! Plus have some rep for jumping in with a map!
