Making these a collection is a good idea! Though I don't think I could make all the hairs, since some don't have a side sprite (Snow White Angela) or are too big to fit in the mod skin resolution limit (Knight of Despair Roland).
Unless I learn how to draw in Ruina style to redraw the sprites, which may take a lot of time.

will there be a collection for all hairs mod?
