I like the perspective here. I also like the two penguins on each side. The environment is very nice, I think I would take a bit off the top as the sky doesn't have much interest.
Love that you broke out the wide angle for this capture, and it really works. The light is hitting that center bird so nicely, and the pose on the right bird is comical. Like the rocks in the FG, the penguins and habitat all around. If you have Nik, you may be able to bring out a little more details in the sky which would really make this image even more powerful. Well seen and executed.
