Thank you both for the comments. The main problem I have with the map is precisely the balance of the decorations. There are very few elements in the map, the three you see on the posted image and an image of two palm trees in the center, plus I have to move the wolf and the butterfly closer to the center, wich makes matter worse. The decorations are not associated with the shaded areas, unfortunately. I have something in mind to solve this, and it is to put the images onto some floating parchments over the sea, and link them to their respective places with thick hand drawn arrows. And yes, the colours must definitely be muted down, but since I'm not a very good colorist, I first begin with natural colors and when I've finished I fine tune with Hue-Saturation.

Thanks one more time.
