Welcome to the hive, Mr Goblin!
This is a very good map. It looks both unique and "warcraftish", and has good attention to detail.
I have a few questions/comments that maybe could improve the map furthers:
-Forest are 99% dense, but there are a few gaps here and there that could be removed.
-I would consider adding tomes at the natural expansions, laboratories and shops.
-The creeps at the merc camps and shops look as if the might accidentially attack units that walk too close. Maybe change the locations.
-Some parts of the map are "linear" in the sense that you can only go forwards or backwards, but not sideways. This also is the case on some ladder maps, but not as much as n this map.
-The distance between the main bases is relatively large for a 1v1 map. Not sure if it would be better to change that however.
In general, I like the layout. It is a very good thing that the neutral buildings are not on the edges of the map. Also, an interesting idea to put to "strong" green camps next to each other.
Still, theses are relatively minor complaints, but feel free to fix them nevertheless. Map approved.
