It is a very beautiful map - all those painstakingly drawn details. I can understand why your wrist is screaming!

I have looked at it several times now, and keep thinking to myself about the amount of dust there must be in the air. Do you think your already superb distance effect might be further enhanced by a very faint and very thin horizon strip of paler grey or pinkish-grey - blended almost entirely away quite quickly up into the atmosphere?
