Most of them I snagged from the official thread.
THe Majority are pieces by rundown, unless otherwise noted.
The shoulder peice is the simplified version edited by Box O Crayons
The Jun helmet is from the Darkness folks. I ended up using it as a base for a sculpt. The attachment is slightly off...,but it's easy to modify the pep after you print it to fit properly.
The handplate is by Ruze789
The forearm started off as one of Rhinocs, but I felt it was slightly off so I ended up sawing off just the top part and sculpting them. If I have time I will resculpt them and remold them so they're more symmetrical/smooth and offer them up for people since while the pep models available are slowly improving I still haven't seen any that I'm truly happy with. Some casts of these are available in the classifieds.
The Cod piece is mostly from Zero202, with some pieces of rundowns put in to make it angle downward in the front half.
The thigh is also by Zero202
Hope that helps!
Sorry I haven't really documented any of my builds lately to help people out. Making videos/photo thigns takes a while and I've been under time constraints. I will eventualyl sit down and go over all my Jun pieces, my overhaul of my ODST, show off the BlueRealm suit I got from Adam, and also hopefully my next project as well.
