You got river issues, friend. While they all connect properly there are three large lakes that have no outflow, and unless they're all salt lakes that's not right. I agree that you have too damn many rivers, which is going to make for some very craggy topography, and I think detracts from the map's overall look. Too busy. Getting rid of some would definitely help. Otherwise, very nice. Nice crisp coastlines with decent levels of randomness, a good variety of landmass shapes, good colors, etc. You should keep working on this. I never thought I'd get my first map done, and eventually it came out looking pretty good. My second map is looking even better, too. So keep at it.
