first of all, this is a good first map.
When I looked at it, I thought it was a TM map, witch should be better, as you don't have any routes, it's a bunch of islands if you know what I mean.
Players spawns are really ugly, and blue has advantage.
But this one is shaded! yay! and the scenery is not that bad too. You could have colorised and maybe changed the opacity your scenerys, the middle ones are good, because you painted them olive, and make opacity different than 100 or 70%.
You got a plus for no or few polybugs
repeating: this map is not flowy at all.
ahh the lower scenerys offers full cover, and are total messy
