Nice images.

A lot depends on how densely populated your world is and whether the map is meant to be a photographic image or an enhanced map.

A photo would have much less land detail:

and clouds wouldn't be seen, they would simply mask the lights.

If your map is an enhanced representation, rather than a photo, then you can have as much land/cloud detail as you want.

Some of your brighter areas of light seem to be too big and too bright in comparison with the Earth at night images I've googled, and your light distribution suggests that your continent interiors are uninhabited, despite the coastlines being very well populated(and perhaps too clearly delineated) the bright spot near the centre seems strangely isolated - no roads or towns linking it with the coast.

Hope that helps.
