As the title states, we need poses for achromatic and melanistic lions! As this wouldn't be a dramatic change, unlike poses for other mutations, I believe that this should be a very obvious addition to the game. No poses for either of these mutations would require a lineart change, only a mask to cover the lion's appearance as it is on the default female pose (which I have grown very tired of, if not obvious).
Anyone who has multiple of either of these mutations knows how repetitive they can seem, let alone how bland! And so yet again, I ask of the developers, maybe think about adding poses for these simple mutations as you have with the complicated piebalds?

I'd love feedback, if you agree or disagree I'd love to know why!
