As usual jbgibson has it all covered. I like the shape of your landmass so far and I'm sure whatever you end up with will be great. I find myself looking at my maps with an eye toward the "story". Something like:"hmm..if that mountain chain is broken there than that would be a great place to put a small village that caters to trade caravans or if that bay is deep and sheltered than a city would naturally grow there.." I am very guilty of jumping around on my maps from coastlines to labeling to mountains as ideas pop into my head. It isn't the easiest way to do anything but it (for the most part) keeps me from getting too frustrated or burning out.
