This is a fab shot - Very Cartier Bresson. Something to be very proud of.
If there was only one tiny thing I think I would change I think I would try and get just a tad more punch out of it with contrast etc - I hope you don't mind but I had a quick go on the low res - To be honest though I am in two minds as to whether the original softer version has that more dream like state and makes it better??? I cant decide but here is a quick version with a little more depth in the blacks....
At the end of the day it's a brilliant picture.
WOW.. i can see why this'd be your fav pic in a long time .. the sense of joy, the wonderful visual delight of this, your excellent processing .. that fisheye is a fantastic tool for a brilliant photographer .. :)
