Nice perch and BG, and I like the low light mood captured. You could apply some noise reduction on the BG, and maybe crop a bit from the left as I feel the perch enters the frame at an akward area (I'd like to see it closer to the corner).
P.S. Although this image seems good don't be afraid to use a higher ISO to put chances on your side sharpness-wise... :-)
Lovely perch, pose and mood here, Kiko. I agree with Dan's suggestion regarding crop and ISO. I might try and open up a little more detail around the eye. Well done
Superb compositional job here Kiko. I like the idea of Daniel about the perch, I think that the composition would be improved if you put the lower extreme of the branch on the left corner. I would try a selective noise reduction in the BG. Well done!
