First and foremost, I am super excited for this script and portrait pack. Realize renaming 3100+ images is no small feat! So take your time :)
I've already been grouping my potential portraits into Fair-pale, tan-olive etc, so like the idea of the sorting mechanics working in pairs.
It would be great to add Skin_Tone: ["SkinB", "SkinG", "SkinP"] where: SkinB = "blue", "pale blue", "teal"; SkinG = "green"; SkinP = "purple". For Dryads, Orcs, Goblins, Nereid and Drow.
Finally (and this is presumptuous so I apologize), both you and Kyler2 seem admirably dedicated to modding the same "construtor.gd", both with similar goals. If you two could work together on this, we aren't going to end up with two conflicting mods, and a little help is never a bad thing right.
