Very nice! But it throws in a few new notions...
Any chance you could change the trees? Flying across London is more like crossing some part of Canada with all those decidious looking trees =)
The slightly darker (wetter?) greens are a lot more like Europe than the usual Californian terrains.
The city textures are a little too Dalas tho - malls, pools, the lot instead of market squares, church spires and village greens =)
But really, the main thing I'd like to see added is a terrain type which has its own vertical elevations included -- hedgerows, stone walls, that kind of thing.
Very nicely done!
