Nice work. Transformers really should give the Decepticons human allies again. I'm still shocked G1 was the only one to do it properly. The closest was Animated or Rescue Bots with their human villains. Prime doesn't really count, Silas was a con for an episode and that was it.
These are wicked! I’m impressed with how quick you manage to bash these out. You mind me asking what software you use? Looks like maybe Zbrush
