I agree with you...the color palette is perfect. Bird, background and perch all match. My eye keeps drifting to the out of focus stuff though. If the bird is a regular here, maybe prune that back?
Love the colors! What a well coordinated scene from a color perspective. The ferns are very cool and different as far as perches go. Image is well designed. I dig that the feet are not covered up by anything. Nice little relaxed inquisitive look on the bird.
