Bats, ive no axe to grind anywhere but it seems you have personal issues with Bob? You do seem rather angry. More that Bob seems to be ignoring your criticism more than anything else. He's entitled to do that though.
Im not sure why it matters so much whether Bob fixes the flaws or doesnt fix the flaws. Its a sculpt. people will either like it and buy it or not.
As for the piece, I think its great, however I think the eyes let it down and it would look awsome with glass installed.
I also believe it would have been better to have applied a machined mask over a sculpt.
I do like the paintwork though!
