For the most part, I agree with DV, though I loved Jaller's mask. It had an calm look about it, but also an authoritative one, which I think really suited his personality.
Ugh, I hated that mask... It looked like something out of a girls' toy line. The great thing about the 2001 masks is that, for the most part, they're ambiguous enough that they can be used for either gender. The Great Rau was useless for anyone but Nokama.
