Well, I'll start by saying these are probably the best Zora sprites I've seen on these boards.
Now I'll move on to the negatives:
>They're too large.
>They're in the wrong perspective (a trait I've noticed in a lot of your sprites). MC very rarely shows purely straight on or side on sprites. There's almost always an angle of elevation, especially in the larger sprites, a category which atm these definitely fit into.
>The outlines are badly rendered; as a general rule, Mc sprites have light dependent outlighting. ie. the outlines darken towards the bottom of the sprite, and to the underside of forms which obscure the light from reaching them.
You might also want to provide 1x as well as 2x versions of your sprites next time.
