I have a default green setting too... he looks very relaxed for a draconis! The others all seem more - er - 'something' that isn't relaxed. Maybe 'scholarly' is the best blanket term - applies to Meiki because he is doing field work in sexual studies! 'Reserved' just doesn't apply to Meiki at all although the others might appear to be reserved. Rez looks friendly without the 'fear' factor of Meiki - as in people who know him fear what he is going to do next!
