You may find that some of the enriched soil under your compost is worth digging out and using elsewhere.

Compost needs some moisture to work properly, otherwise it will just be a moldy mess. If it's too wet, it will be a stinky anaerobic soup, which is not ideal either.
In any case, rainfall will leach nutrients into the soil below. I have used old tarps to hold moisture, but it also helps hold nutrients at the bottom of the pile.
I discovered accidentally that the best location for a composter, fast or slow, is over top of soil that you intend to plant a year or two from now. That weird leached compost liquor is stinky gold.

With the mix you have, the stuff at the bottom should be beautiful. And the half-done stuff will be perfect for squash piles.
