Welcome to the board, Fusblr!

You have a very interesting map going on, which is heading in a good direction. That said, the overall shape of the map seems too determined by the canvas, making it look unnaturally rectangular. A way to fix this would be to increase the canvas and redraw the outer edges of islands/continents so they spread better, or do it the opposite way and eat away some of the coasts. Also, you could simply have some of the landmasses extend beyond the edges of the map.

There is also an odd group of waves surrounding the two islands westward of The Smokelands, that overlap with each other and also into an island to the south. I see similar, but much less noticeable, patterns surrounding other medium-sized islands, specifically those in the Kirthari Sea, the one where Dorstad Fortress is, and those two westward from the Isle of Wyrms.
