I am for the most part a bird photographer, so my eye isn't that good with wildlife but here goes.
It looks as though this seal is leaning against another and I like that, as well as the way you have formed a design with your composition. All the "war wounds" really add interest in the FG seal. I love the way the sun appears to be setting in the seal's eye. I think I wish for a tad more sharpening on the seal's head but not absolutely sure about that.
I like the way you framed this, Ian. Good lines, shapes, and soft light make for a very tasteful composition. Wonderfully expressive eyes. Nicely done!
