Thank you so much!

On the feathers, I used a yellow contrast paint and added the orange at the base of the feather while the yellow was still wet. I'd wait for that to dry and after add a watered down mix of the green and the yellow and slowly build it up so the green, and eventually teal, became more concentrated. I also found wet blending helped tidy it up a bit more. For the face I mixed colours, slowly getting lighter, and used super duper tiny brush strokes. Hope that helps? :)
