So, this is another very good map. There isnt anything that I'd say is wrong, and there is a nice idea with the cliffs behind some creepspots, which could be used to lure the creeps/steal lasthits. It's also sensible that those are only around small creepspots.
Some other questions/suggestions/comments:
1. The lvl 2 permenant at the expanions feels underwhelming, but a lvl 3 on the other would feel quite strong. Not sure about what to do. Lvl 13/14 spots often feel like this to me.
2. For my taste, the map lokos somewhat too "clean", in particular the shallow water areas. I would have expected some fishes, plants, clams,.... There is lot of attention to great detail in other areas however.
3. I dont really see any resemblance to NI.
4. Some of the trees obstruct the view for some creepcamps. You can avoid this by scaling down the trees on the south of the camps (just select them and press "-" on the numpad):
Currently:

After downscaling:

5. The northwest part of the map probably wont see much action before the late midgame. Maybe the shop/labs/market could be a little closer towards the center, but of course this would be a lot of work for a not-at-all guaranteed improvement.
6. Some critters could be placed further away from creepcamps, to reduce the risk of them wandering into the camps, especially at the mercs where the creeps dont sleep.
7. The lvl 14 camp south of the tavern has a critter nearby, while the respective camp east of the tavern doesnt.
I'm sorry for the delay in reviewing the maps, but I didnt want to review anything while the contest was ongoing, and then the w3c map stuff took most of my attention. Anyway, map
approved.
