I just started working on this years costume which is going to be a transformable Optimus costume, I've got almost all the engineering done on it. It's gonna transform almost exactly like g1 prime. In order to do the arm transformation my arms are going to pull out of the costume and tuck into the chest piece, and the chest piece will pull wider in order to accomadate my arms. At that point the entire chest piece will flip around so the back is now my front, at which point I can just sit down and the legs will stay relatively the same. I've decided to keep a blog on the progress of the costume, plus it gives me a reason to play with my camera. http://tfcostume.blogspot.com/ I will try to update it daily as the costume progresses over the next couple months. I'm hoping a lot of the costume will come together fairly quickly since I'm basing it on the last prime I did. I'd love to hear some feedback I think this belongs in this forum though it's a bit different from traditional art. This will be my second transformable costume, last year I did a transformable Grimlock.
