I agree with Karl - the details are amazing. Wonderful capture of this often-elusive species. My only nit is that I find myself wanting to see either the whole bird or a bit less of him. I don't know how large a crop this is, but if it would hold up, I'm wondering what it might look like cropping right and bottom to eliminate the oof vegetation.
Superb detail and colours, Enrique - such an attractive image!
Great background too, in terms of composition I tend to agree with comments above - a tighter crop to eliminate the vegetation would greatly benefit this frame.
