I really like the angle you captured with the 3 profiles positioned just right. I wish the image were sharper; none of the birds appears to be in focus. Surprising considering you were using f/11. I'd try to lighten up the head area of each of the 3 birds.
I too like the symmetry here, Yves, but I agree with Doug that the whole image looks soft. I agree also about trying to lighten up the shaded portion of the three heads.
