I like that border, nice and clean. And your terrain looks fantastic, I love the lush river valleys. Very good job

The title is pretty hard to read I think, might be worth testing a simpler font there. I also think the continent's overall shape is very rectangular – the coastlines are great when zoomed in, but looking at the whole thing, it seems quite adapted to the paper. There's a peninsula extending into every corner I don't know how easy it would be for you to change the shape, but personally I'd try to make some cuts to the landmass.
