What a special moment you’ve captured here! Your image is sharp where it matters most, with good light in the eyes, well done! The image is slightly overexposed, but hey, we can’t control the light in nature. A suggestion to improve your image is to crop more at the bottom to create a better balance in the frame. Although you want to show the catch, the lion, which is the main subject, is the smallest in the frame. I would also pull highlights down on the left side, which is very bright. Do that and post again.
