Seriously thinking of redesigning Castor to look like this. A bit more minkish, a lot more adorable (which goes hand in hand with the mischievious streak) and well..I admit, easier to draw. :) I like thw two-toned nose, so either way I think I'mna keep that.

This scanned really light.. the muzzle should be gray. x.x

Anyway, what do you think? This or the first design? :)
