I saw a few Maul's at Excel. Was your face painted or was you wearing a mask. There was a good one on the Dagobah photo op. He did a round-house kick in front of my Dad's camcorder! It looks great on the video.
I myself wanted to go as a Darth, the 'other' Darth, but my costume wouldn't fit in my case!
Ah, well, let's hope the GMEX holds a SW convention of some description, so I can wear my Lord Vader costume in public & not just round the house
