It was an accident, honest! I asked Kev is he wanted it back but he said I could keep it. It is rather nice though isn't it?
Trust me on this; unless you've been sculpting for an hour a day every day for the last 6 years, you're not the worst, you just haven't been doing it for as long as I have. I've just spent the last 20 minutes pulling faces at another failed attempt at a female face.
To make banded armour, just keep doing what you're doing and refine your technique - maybe use half the amount and see how thin you can make it. I've got a Miniature Mentor video (Frightmare) that shows the process but the sculptor uses an odd technique - I think he added tiny little strips instead of just pressing in with a knife, I'll have to look it up.
