I think its clever thinking to cater for wider group of people. It is clearly inspired by what Sergei Popovichenko designed and later Tartar produced with a Knight from the Crypt.
And I am not sure if human knight is Lasarus order, zombie knight should be - surely its what/where one's fantasy takes it?
AND... a proverbial spoon of tar in a bucket of honey:
I really dont like human person's mouth, anatomically.
And with zombie knight I expected at least a little of some clever weathering of the rest to go in line with the character.
Yes, modeller can do what they want with it, but I am making an assumption that alot of modellers would not feel confident doing it themselves and surely sculptor too had a vision of what it should look like...
I like an idea of two heads, I would like it even more if design allowed easy swapping of painted heads to change whenever you are board™ with previous one, and enjoy both options.
And another thing....if the BUST (!) doesnt float NAP's (!) boat
, then sweet Jeebus, you are in trouble...
