I read Grimm's Fairy Tales Cinderella and I liked this scene. In the story the bird gives Cinderella her outfits. This is how I imagined the bird ^^
It's kinda like, Disney meets "real fairytale", so the Cinderella is a bit Disney-ish and the bird kinda like something you could see in a fairytale book.
EDIT:
I made it a bit darker, because it always looks lighter in DA than my photoshop :/ EDIT2:
Interesting! I definitely think you got what you were after - and I can also see the bird as a form of the Fairy Godmother in the Disney version the way Flora, Fauna and Merriweather have bird forms. (Faves and recommends) Keep it up!
