I've been working on Balthier's model for other people to animate with.
It's still a basic XNALara to SFM port, with only bone posing, but a rig can now be applied (rig_biped_valve_3spine and, alternatively, rig_balthier). It'll be up on SFMLab soon but you can also get it from here: Edit: Latest, improved version now available from SFMLab.
If you give this model a try, please let me know if you come across any errors.
Edit: Final votes for the monthly poll will be welcomed until Monday evening.
