I've been doing a bit of work on textures lately, and planning to release a few texture updates for Gold+ patrons soon :) This will include a nude pack ;o
The new harpy colours will give you a feel for how hair colour will effect monsters down the line. Right now there's two variables, variants and hair colours, the variants change the texture on the monsters body, where the hair colour changes their hair (obviously) and any other special parts on the monster (wings on harpies, tails on neko, scales on lamia, etc)
Later on a face variable will be added when I make a couple different possible face textures for each monster.
