I did a long review thingie, and I can maybe give ya the full thing if ye want, but here's a short version of it.
Great map, though few flaws. Distances between mercs and gold mines are not equal for all sides, making certain gold mines more valueable.
Some players can AoW Creep orange lab camp, others can't. Remove unphatable terrain and add some trees.
Total distance from base to base is a bit large. Mostly favors human or expanding races in whatever matchup would be occuring, also due to easy expansion and multiple choices.
Limited long/route paths to flank enemy. Makes holding a choke very valuable. Again favours defensive races in match-ups.
Main base lab, supporting yet again human and races that are behind on tech/lumber, and gives easy access to reveals.
Not sure how one would fix above balance, without major changes. Perhaps swap merc/lab? Dunno.
Asthetically the map is perfect. Would not change a thing. Blizzard style at it's best, which is what any melee map should aspire to. Not sure about theme, and I like orginality, it is a bit bland and standard. I'd least like to mix a few terrains, but this is not a negative, just perhaps a suggestion for future maps. Tileset was used to its fullest and well done.
Random idea, since not all map seemingly used. Island expansions might be worthy of a consideration.
