Hi Juan,
BG looks ok to me and the color compliments the bird nicely. Head/upper body seems a bit soft compared to the back part of the bird. Perhaps a little last moment turn of the head from him?
Steve
I agree with Steve that the plane of focus is in the body, so the head is slightly soft. I think the f9 aperture saves this. There are lot of details, nice colours as well.
I like the alert pose, eye contact and BG. The critical focus seems to be on the feet. I sharpened the head selectively and converted the image to sRGB. A bit more room all around would be good.
Thank you guys for all the help and advise, now seen the picture over and over I can see that the focus is on the body and not on the head.
Alex, thank you so much for your repost, you did a great job.
