I'll probably be the only one here, but great choice in shoes (even though they don't fit this costume, haha)! I believe I have the exact same model and love them~
As for the costume itself, I'm personally not a fan of the hat. It matches in color, but doesn't seem very Harley or Ren faire to me. Maybe look into headwear that's more one or the other? You may even get away with the full out jester hat :P
And this isn't a critique, more of a possibility, but it would also be interesting to see if you could work gloves into this outfit, since that's another one of Harley's trademarks. Otherwise, looks good.
