Thanks guys. I was looking for a single credit for the FR map, but even Wizards credits all three for it:

God, I look at these guy's work and realise how much I still have to learn. That was a good shot of inspiration before heading into a day of mapping...

@Thebax2k: More maps are always coming. My new website picked up commissions for two poster maps, I've got the summer Map of Fantasy for Kobold Quarterly, and a bundle of maps for Halls of the Mountain King for Wolfgang Baur's Open Design. So no shortage of maps in the pipeline
