If you had settled your second city with overlap with your capital, you could have improved all your food resources and worked them at all times. Right now you have a city on the copper that lacks food, and you have food resources around your capital that go unimproved and unworked.
A goal for your early expansion should be to get as many resource tiles as possible improved and worked, since resource tiles are so much better than non-resource tiles.

I have to run.
