I'd have liked to see them less central in the frame, in this case more to the left. That said, they look perfectly exposed and the wing motion blur in the second is great.
K9- this is my new Canon 100-400. I love it. More keepers in 2 weeks than in 1 year with the Tamron 100-400. Now I feel I can work on things like avoiding centering everything. Lol.
