Pretty pose of a bird that's tough to shoot. I always find it hard to get good balance between the black and white on a chickadee, but your exposure looks great. If I had to find something to improve, I'd like a tiny bit more room on the left so that the tail isn't so close to the edge.
I like the composition, particularly the texture of the background and how it compliments the perch. Balance of the blacks and whites is spot on to me. I agree about the "tailroom", and the head angle in not "optimal", but I think you done real good on this un.
Hi Pierre, I think you've done a great job with the soft lighting, details and sharpness on this. I also love the way the background colours compliment the colours of the bird. I think that a little more room all around would be beneficial.
Pierre, this looks to be well exposed. I like light and the soft BG. These guys are hard to get with a clean perch and an uncluttered background. Nice job! :)
