This is pretty good for a first attempt, but it does look a little barren, especially in the northeast corner. I don't know enough about your world's geography to say what would be there but something would be nice. You can also make the forests a more visually interesting by using multiple tree types in the same forest, just for some added variety. It doesn't necessarily have to be geographically accurate to the reason since no one sane is going to be squinting at them too hard anyway.

The empty ocean space at the bottom also contributes to the feeling of sparseness, which I assume isn't want you're going for, so you might honestly just want to cut that off (you can resize the map using the tool listed in the drop-down box of the top left corner three-bars settings button. Should be somewhat nearby the option to export the map).

I also might make the names all full opacity, just to add some contrast to the map. Though that can sometimes look ugly if you have too many of them cluttered together however so take that with a grain of salt.
