Looks pretty awesome. Got a few suggestions though.
a) Theres LOADS of build space though, maybe too much. You could quite easily make it 3 v 3 IMO.
b) Needs trees.
c) The far left cliffs are way too repetitive, theres also a graphical error there where a part of the cliff is missing.
d) Theres no need for the southern middle derricks IMO either, kinda gives them an advantage. You could add more things there... like a little fishing port or something, giving garrisonable stuff to play with.
Theres also more water on the North/North-East sections, making it feel kinda weird. You should move the island to the centre and it would feel better. Other than that, looks like another quality map for the 'Hogster'.
