This is a really cool charecter. I don't know enough of the lore to really comment on its uniqueness but I like it. The mix of the bird and a human estetic is spot on and it fits nicely into the Zelda universe I think. I also like the color choices with a nice blend of greens and reds that give a very balanced impression. The choice of background colors fit excentuate the colorpalette of the cloths perfectly as well. Really nice and I love the abstract background! I might borrow that idea from you in the future! :)

When it comes to the execution I can't really fault it. The fact that you've worked with a gradient in quality with higher quality in the face of the charecter is great! Wished I had that fingertip feeling for how to do it as it creates a natural focuspoint in her face and in particularly those eyes of hers that give her so much charecter! She's really like, "so, what are you gonna do about it?". Really cool.

If I had to give some critique I think that some of the shadows around the livery could have been a bit smoother and perhaps not quite as dark. I also would have liked to have seen a bit darker shadow on the wings to separate the "arm" of the wing from the feathers a bit more. Finally the "wrinkles" or whatever you call it on the feet could have been a tiny bit darker. However these are all nitpicks as they at the same time provide the aforementioned focal point but still my motivation for 4.5/5.

Overall a really cool charecter and style. Congrats
