Seabed

Zergs cant effectively wall off with 3 evo chambers: https://i.imgur.com/u8s5V0K.jpgv
I'd replace the large rocks to the rich geyser bases with a 4x4, so armies can path through the small bridge in the center.  https://i.imgur.com/24TGnb9.jpg

This cliff could probably be trimmed back a bit to give more space for armies to fight. https://i.imgur.com/OgjSpjF.png
The XelNaga towers might be a little too strong of a position, having them here might keep them important but allow maneuverability https://i.imgur.com/XeynG0j.png
The biodome frames being slightly off symmetry will bug me forever pls fix
