I haven't played FFX much, is it bigger than Cloud's sword? Or Squall's when it's like 15 ft long and glowy (that big thing is evil when you fight him in KH).
Anyhoo, from what I've seen, colored this would look like a profile picture from the official website.
As one who has played Final Fantasy 10 far too much, I think I have a fairly informed opinion when I say this looks pretty close to the original. Wonderful work on the costume, even included the jug on his side.
I'd love to see this one completed, it would be a sight.
