Though there are a couple of issues that you can do to make the map better - like the rivers splitting on left side and some minor points where your repeating texture shows a little. I think this is a great map and nice bit of art and I will give you some rep points to start your rep pip off in the green zone. Also some rep for posting the tut link on the rivers which I was going to do but now I don't need to. Thats great stuff - im glad you already found it.
If your interested in getting rid of repeating texture edges on seamless tiled textures then where you have one texture put in three - all the same image but tile them with different resolutions. Best to make the difference between res's in factors of some prime number. Say 100px x 100px then next one 133px x 133 px and then another 179px x 179px. Then they will not repeat in multiples and not show the edges so clearly.
