Atmosphere - 1/5 - Map presentation is bad. No map preview. Despite the fact this map is about night elves and treants, the loading screen is a picture of humans fighting orcs. Change it.
Information is present in the quest menu, which is good. Btw, the title of the quest 'Object' should be 'Objective'. You don't need a quest title to tell the version of the map. Change the text of the loading screen's "Loading Screen Title" to Tree Wars v0.13.
Barely anything custom inside this map, and you call this "fully developed"? You know, for things like the Treant Caster, you can import other models.
Placement of icons are bad, eg. the buildings in the building card are scattered everywhere. And the Ancient of Treant's unit training icons are misplaced (it should be weakest/cheapest/basic unit from the left to strongest/most powerful to the right, not the reverse).
Gameplay - 1/5 - I'm sorry, but what you did was take the night elven buildings and removed everything else, and then put that in a poorly terrained 'map'.
The terrain is flat and boring, and I know you tried to make the map symmetrical...but the players on the right edge have more building space. Also instead of just covering the border of the map with vines, fill it in or block it off creatively.
You only had 1 race (the Treants) to choose from, and it didn't offer much of a techtree.
Just a bunch of ancients ripped from the NE race, and 5 random units, 1 of which also from the NE race. And the custom units didn't have any fancy abilities or attributes to compensate for the amount of units in the techtree.
I think the Wisps were overpriced slighty. Especially in the beginning, as they take a while to harvest lumber, and they are used up in building structures.
Get rid of that stupid Headquarters building, and instead spawn a Tree of Life in the beginning. This is to give a starting food cap and to remove the revealing thingy.
Fun - 2/5 - Yes, you can have a good time with the miniscule, uninspired techtree, however that doesn't mean you have put any effort into make this map unique and fun to play.
I mean, you've given players nothing to work with! They can't make up any fun strategies, they can't play in a variety of ways, they're stuck with an empty map and spamming Treant Footmen dudes.
There is no AI as well, which means no single-player.
Storyline - N/A - not story-driven.
Overall - 4/15 - [1/5] - I hope you keep improving on your mapping skills, as this map was appaulling. I know this is your first map, so don't fret. And if you're going to answer to my review by saying "this is just a wip and I will be updating it", there is a clear rule against works in progress or unfinished maps.
This map must be rejected because of the (lack of) content and the poor gameplay design/innovation.
Technical - Description is short (maybe because there isn't much to describe). The map type isn't Arena, it is Altered Melee. Category should be Medieval/Warcraft.
