This isn't really art, but this seemed like the best place to post these pictures. This is an Optimus Prime helmet I worked on two years ago for Halloween. I only got the head done so I went as Optimus Prime - In a Hawaiian shirt. I did match colors though using a red hawaiian shirt. The head is actually a blown up version the the 20th Anniv Prime. I took calipers and made measurements off of prime's head, then scaled them up to my size in autocad. (All those years of engineer school had to be used for something) You can see the toy in one of the pictures to give you an idea of how big it is. If it seems really big, well its because I'm a big guy. About 6'7" and I needed it to fit my head. The head itself if all styrene and PVC, no cardboard. My friends have been on me to make the rest of him, but I don't have the motivation right now, this took enough of my time as it is. I would like to go back and add more detail, but for now I'm happy it sits on top of my desk.
