Quote - Would it be ok to make textures just for one version, or should I make it for both? 

I think it's perfectly okay to pick the mapping you like best and make a texture for that. Except for the mapping, those versions of Antonia are completely identical.

At some point, I hope to develop a tool that can transfer textures between different UV mappings for the same figure. But probably not before Antonia has her complete set of expression morphs and such.
