I'm now beginning to believe that Jiaou's colour-coding is completely unreliable and arbitrary (I'm becoming more and more certain that the '12D-BS' I own is a mislabelled YS due to it's yellowish complexion, but I only have a single 11BS and a single 10BS to compare it to, and those are both completely different skintones to each other as well to add to the confusion). That said, here's a comparison lineup (with apologies for the lighting):
Left to right: Jiaou 12D-BS, Jiaou 12D-BS01, TBL M30, TBLM32 (didn't have an M33 to hand unfortunately)
Natural light:
Flash:
This is not to be taken as any kind of comparison guide to height by the way - the M30 is wearing boots that make him appear slightly taller; the M32 is not only wearing boots but also ankle extenders that make him appear even taller than he is to begin with (both figures are also padded at the midsection to bulk out their 'waspie' waists).
The design tweaks I speculated on earlier between the two Jiaous seem to have been entirely illusory - they're exactly the same figure I think, just in different skintones. As you can see though, the BS01 is a decent match for TBL's male suntan.
As for the sculpt I chose for BS01, while I really like it in terms of design, the total lack of a neck means it sits very low on a seamless body (but that can always be modded if you're brave and/or patient enough to try).
So: do I recommend the Jiaou 12D?
It's fine as a one-off, but I don't need an army of them.
