Yes, airhead GS rules, and it will take tens of years if ever anything can beat the sheer authority of tastefully modded GS like yours here. I liked a lot of your versions, BMW badge white/blue colour scheme on the chassis and on the bench and that reflector on the fork. Too much praise so have toi criticise too, I would had liked to see a bigger headlight, it could contribute to the utilitarian authority and give some "all seeing eye" punch to the bike :) In addition to giving more light.
Some day I am gonna buy a book which tells me everything of develepment of GS BMW. I want to know what the engineers thought.
EDIT: Those two GS are more than bikes, they are like faithfull assistants with strong personality and character made to serve well in both good and bad times xD
