Update:
Gluing the forearms.
Ears in place. Man, those were hard to trim. There are no guide marks, whats so ever, on the TM ears.
All upper body parts done, including straping system. Buttons on AB not yet glued.
Rivets on the left side with snaps on the back. I might use velcro to close the left side instead of snaps/elastic. On the right side (not showing) theres a single "button" (I used the bottom side of a male snap) as there should be. That side is closed using velcro.
