* The original canopy section was removed, since it's not there in the movie version, leaving the canopy itself only. * The whole chest section was redone using mostly new parts to get the right look (much bulkier). I used parts from other transformers, some model kits and a couple of custom made parts. * The middle section (the one that's directly above the canopy) was resculpted to be permanently open, with a few tiny mechanical parts and wires on the inside (those wires are only visible in a few scenes from ROTF, I had to take a few screen shots to see them) * A few parts were added on his neck as well, to form the "collar", and a few more on his shoulders. * His neck now has a ball joint. * His missile launcher now has the added "wings". * Several wires were added on his arms, instead of just paiting the sculpted ones, for a much more realistic look. * Articulated fingers were added on both hands, and a ball joint on his right hand. Each finger has a tiny spike on top, just like the CGI model has. * Engines and more jet parts (wing parts, actually) were added on his back, and some unnecessary bulk was removed. * His legs are heavily modified, with tons of new parts added, to get that overlapping-transforming-panels look. * The final touch is on his head. I resculpted his eyes for a more accurate and more evil "look". And last, but not least, each eye has its own LED now, and they're visible even in day light!
