Impossible to tell what is deep water on that. Please use a different texture for underwater terrain or colour the water or something.
New version, so much better
EDIT:
After testing out different teams and starting spots, I'm pretty much convinced Proteus is most suitable for a 1v1 map.
Any more than 2v2 feels crowded and in 2v2 you're either as far from your ally as you are from your enemy, delegated to a cliff spot or have like 10 free mexes in your base.
Also zhtuues are really OP as frigates have trouble shooting up the shores. But that's more of a game balance, than map specific as the shores aren't that high.
EDIT2:
Got a complaint from one player in game that he could not distinguish the ramps on Twilight Hill due to slight colourblindness, just thought I'd let you know.
Otherwise it has a nice "StarCrafty" feel to it with the chokes and ramps. Very intel heavy since if you move units to the wrong place, getting them back in time is nigh impossible. Need to get more games on it, especially 2v2, should turn out interesting.
Liking Metir the best out of these new ones so far. At least it makes for one hell of a 3v3 map where you get action all over the place, very nice. *thumbs up*
It's not too badly zhtuue favoured either because of the size and the mexes being close to shore so you can raid them with frigates too.
