I can't see your save right now so I probably can't see as much of the map as you have revealed so far, but:
I would sink a hammer into the 'mids asap, then get one more worker/settler out of the cap, and then make/chop the mids while the stone city uses the second corn so that it can pump more workers/settlers. Try to get another decent work/settle pump going before the mids are in (maybe up north around the pigs/corn), because once they are you're going to want both corn back in the cap after that, and going to want it to grow a lot.
