I'm not sure. I'm torn between a couple styles. I'm thou roughly in love with Max's Oraven map styles, and I also love the way Viking did his most recent map of Skenth. I figure a pure overhead map would be the most informative and realistic - but it is the fictional world of a trilogy of novels. So I'll probably go a bit more artistic. Know of any cartographers that have artistic overheads I could check out for inspiration?

Oh and thanks for the info about Britain. I considered attaching it - but my time period for the flood is only about 4500-6500BC (haven't chosen an exact date). I want to use it as the mystic isle of Avalon. Thanks though!
