I'm no archer. but that right=hand location just looks wrong. It's not anchored to anything, wafting around in mid-air. Probably she'd draw to her lips, rather than the ear/jaw reference associated with the English. Which also eases the bow-string problem a little. That looks a shorter bow too. The centaur myth is from the Greeks, and probably reflects some partial knowledge of the horsemen of the asian steppe, so a shorter bow of composite construction would be correct. And not the English lock -- they used a thumb ring. And, yes, I had problems posing Vicky 3 with Diviner's longbow. But the ancients didn't have to struggle with the silicone factor.
