Stella is a fluffy orange bird with a fiery expression on her face. Her wings are spread out and her beak is wide open, as if she is about to yell. Her feet are firmly planted on the branch, with her raised foot giving her an extra boost of power. A hint of yellow around her neck adds to the intensity of the mood. To emphasize the emotion, you might color the leaves of the tree a dark green and the sky a deep blue. Give Stella a bright orange plumage, with hints of yellow and red along her wings and chest. To really capture her fiery anger, you could use shades of yellow and orange along her eyes and beak. To finish off the picture, you could use a combination of light and dark brown to colour the branch and add some texture.
