bird legs || bird feet || bird metatarsus || double knee

I've always been frustrated by the poor execution of things like bird metatarsus in standard models. This is the backward-curving part of a bird's feet. I find this part very cute and adds character to the character. Especially since there are characters who are hard to imagine without it (like Stolas or Stella from Helluva Boss).
This is my second model, and I hope it turned out well. For training, I used 40 different images instead of 20.
