That head... genius! Love how smooth it all looks, those HF cladding parts work wonderfully here. I really like that heartlight(don't know if that is what it is, but I'm calling it that), And I really like how you used the Exo-Force parts and the claws to make the barrel of that arm-cannon. Plus the translucent lime green part inside. I'd love to see how you put that together.
Yeah that happened to me once, built a cool head, and then I was like "well fuck I gotta do something with that I just gotta." It ended up being this little MOC by the name of Mototaur, ya know, no big deal.
