Looks good. Suggestions: Try to taper the beginnings of the rivers some (looks like you're using a mouse instead of a tablet, but if you go back in with an eraser - delicately - to the sides of the river beginnings to just taper them a bit, it'll look nicer). Erase the rivers where they overlap into the ocean area. And maybe thin the forests a bit where the rivers run through them... remember it is a map, so it wouldn't be very helpful if you can't see where you're going.
