Yes, Shellhead is my secret elf. He sculpted the doom gloves, the "creature" head, the "flattop" head, and more. He also re-sculpted the Hulk arms
and legs to achieve the new articulation on the Large White body.
His day job as a Disney employee keeps him too busy to do more
custom work - so don't bother him with custom requests.
By "secret elf', do you mean that in the Santa way; you didn't pay him?
As an designer/sculptor, I'm not big on requests. Too many of them on the www. Commissions on the other hand...
