My favorite is the female Cardinal... The muted colors are composed very nicely. I would crop out the bottom right corner as the shadows take away from the brighter subject. There is also a large branch in front of the bird which is distracting but we can't take it out of the photo, but she can be aware of objects in the foreground that distract on her future photos. Wildlife photos are challenging! It is much easier to shoot a buck with a rifle than it is to take his photo in good light!
