Steve, that is one heck of a piece, you really have captured the essence of this ship's launching.
My only crit is a minor technical one. The width of the stripes on the bunting looks uneven in some areas (wouldn't the colours be of the same spacing?). Though you might have done this on purpose to convey the effect of draping and folds. All in all though, this is just a wonderful job you have presented here.

Jack
