Looks really good, much better than the usual fare I see at the UK Games Day, although I think thats slowly improving over the years. It seems the US have had marines walking around at the odd Games Day for a while now. Where as here in blighty we seem to have a few guys dressed as Guard, Bone if he's there and occasional scantidly clad women as Witch Elves or Sorceresses.
Much more interesting costume here I say, looks like it was worth the effort as well. Grats on your win.
