Re-visiting and re-working

I have been going back to some older paintings I wasn’t sure I had finished. This one started off as an experiment with techniques.

Pretty soon I could see a map appearing. Then I got thinking about global warming, ice melting and all that jazz.

So, I added some water flows away from the ‘island’, then some scattered city lights here and there (because I think our population distribution is going to change dramatically in the next 50 years) – and finally think it is done.
