Playability: a very good and playable map, if I ever want to play a free build map, I almost always choose this map to play, because it had much open spaces, much resources and, just a very good free build map. I even think that a 4 is justified.
Balance: All the resources are good balanced, in a good distance of each other, and for the rest I just set the score so that it doesnt effect the overall score that much.
Creativity: I've seen some creativity in this map, but it doesn't really jump out in some ways, which I think is a bit hard because you don't have any events, 1 tip I have to give you: place a signpost. But sice this is your first map, a 3 is certainly deserved.
Map design: Hmm, here we see one of the weak points of the map: map design is good, but it is average, it had very much bare areas and not much transition between 2 areas, I liked the river, but no more then that. However a 3 is deserved here to.
Story/Instructions: Too bad: not much story (correction: almost none). Always include a story, or it gets the rating down, like here. If I dont find inspiration, you can always ask for a story, this is for all the players out there.
Balance (revised): Normally a 3 would be given here, but a 2,8 would be to less, so I decied to give it a generous 4 (let's say: +1 for spreading of resources), so it evens up to a 3 as a overall socre, which is still to less, but hey ...
Overall: All the players who want to play this map: Do it, because it's a very good free build map, it allows you to make a strong castle with a very strong economy (hint: place a signpost in the editor).
