Hola Tomas,
Very nice subject wit a strong diagonal composition. I may desaturate the blues on the sky a little and a bit over the shoulder head turn would have made this a stronger image. Thanks so much for sharing.
Fabs has covered the two main issues for me: sky colour, and HA. Of lesser concern, but still something to think about are the steepish angle, and the harsh light you had to contend with.
I like the colours on the bee-eater itself. Exposed best you could for the harsh light, and sharp as posted.
