Here's some pictures of my custom Kre-O builds. All built using only pieces from the respective sets, no borrowing from other sets or use of lego etc. Ratchet (based on artwork from IDW's '-ation' comics) Bumblebee (went for the G1 'car-roof for a chest' look) Optimus Prime (about as G1 as you can get with such a small set) Prowl (still need to fix the proportions but almost there) Starscream (first attempt, not really happy with it, gonna try again) Sideswipe ( first is a stocky G1 type, the second is based on the Classics toy, not decided yet which to keep) Movie Optimus Prime (Based on the ROTF Leader figure, with rifle and swords) All comments and criticism welcome, always trying to improve them. P.S. Please excuse the dust!!!
