Hi Raul,Such a pretty little bird! The colours look fine to me and I love the juxtaposition of the bird with the pink flowers. The bird is also beautifully sharp. As you say, the BG is very busy.
Nice capture of a beautiful bird. The colors look good, otherwise maybe a bit oversaturated. As you said, I wish the bg was not busy. The OOF feather in the bottom left corner is a bit distracting as well.
Other than the busy BG, the bird is very pretty but I feel it could use a bit less saturation. IF this is OK with your post processing ethics, you coulees blur and burn the green BG a bit.
There a tutorial on how to on the Tutorial Forum, on page 2. Un saludo :)
