Great layout Zip. I like the oils better on the left side of the map, the engis will be able to capture them quicker and not be eaten --securing early game eco considering there are no gems at the start. And for the right side of the map, I would put Air Tech ports and perhaps a smidge more gems adjacent to them so you can still have that interesting ridge thing going on. The map would run a lot like heartland but with more split/dynamic potential with paras and cliffs.
Easily official material. Make a 2v2 map next ; )
