Just make the main ramp one space wider. Also for the xel naga towers I would suggest putting them on the opposite side of the thing cliff they're next to. That way it gives wider vision. Right now about half of it is being wasted looking at the water.
EDIT: I also feel the left one can see the gold expansions more than the right now making it slightly harder to take that expansion as you'll be more likely to see workers mining.
