I'd highly prefer you draw mantafae with their newest anatomy because I got in trouble with them a long time ago with their old anatomy. (you can check out my recent batches to see the newer anatomy)
The ears and neck are fine to go back to the old style but the hooves are rare and can't be used on "free to make" ones.
And mantashark have several forms
-Anthro (humanoid anthro/and a more natural looking one to their species
-Merfolk
-Centaur
there was one more form but I ended up throwing it in my storage //it wasn't super important anyways
