Great colour balance on 'Old Mitsu'; for most designs I'd never think about mixing green, blue, and red together in that fashion, but between the low saturation, the dusting and the other detail elements, I think it works. I also particularly like the white chest hair: which dirt pattern is that?
On a side note, I've been using the plumes a bit myself for creating various facial hair configurations--though of course its really only good for creating static designs as the movement independent to the facial structures makes the effect more or less a mess during any degree of activity for the model. Nevertheless, it has had me feeling maybe we should petitioning Project Soul for some custom beard objects in the editor. Of course the real solution would be more facial models with more varieties of facial hair at more variable lengths--but given the short shrift the editor has gotten during this game's post-core game continuing support, I'm certainly not holding my breath on that. Even just one or two hair-based objects with more individual filaments than the plume has could open up lots of opportunities for both facial hair and custom top hair (and probably a great deal of other possible applications).
