A Laughing Kookaburra having just taken off.
1DXII 400mm F/2.8L II & 2XIII 1/2500 f8 iso800
CCPS2017 slight crop, added some canvas in front of the bird, light sharpen.
I see a couple of repeating patterns at left, but only because you mentioned adding canvas. Great flight pose, and low to the ground! I actually like the shadow too. Strong light with a "colder" look to it - you could always add warmth in post.
