You're armor is looking VERY nice and you seem to be getting the pieces completely finished pretty fast so I wanted to ask you, are you NOT using any bondo for some/all of the pieces?
I just want to know because time is running short for me and I want my armor to look really nice (especially after all the crap I went through to make it how I wanted), but I fear that the bondo and sanding will take up too much time and I won't have my armor finished in time. Although, I might still use some bondo ONLY on my helmet at this point.
As for people cutting the bottom sides of the torso off.........I don't know about that. I think every time I have seen a finished costume, everything was how it should be. I don't recall ever seeing any part of the torso modified to allow for putting your arms down better.
