You're pictures do work, though there is some unnecessary code in there too.
The bubble bath IS smaller than the 12" figure, but it's such a small difference in size that it's barely noticeable. It's definitely a better sculpt than the 12" figure though, and more accurate.
Still, I'll be interested to see what you come up with. Especially if you do the other Commandos as I've NEVER seen a lifesize representation of ANY of them.
