Hi there Pantso, welcome to the Guild! Not bad for a first post. I think the crumpled paper effect is perhaps a bit overstated. Maybe if you were to decrease the opacity of that layer a bit. The rivers might look more natural if they were tapered. The colors look good overall. Given the crumpled paper look, it might look nice if you were to make the edges and sides of the map border look a bit warn, burnt, and/or torn.
