If you haven’t seen any of Krexx’s sculpts, then you have been out of the game for far too long. He has been sculpting for several years, and his work has been available on many casting sites (currently including the Angel Forge).
Below are some of Krexx’s ARAH sculpts. If you interested in these parts, you can contact Krexx on Facebook and ask to join his ARAH Sculpts group.
Krexx also sculpted some alternate heads to work for both the Storm Shadow and the Sniper bodies.
