A real cutie Gus! Very nice, simple image. with lovely colour. This is definitely a greeting card image with lots of space on the right for the words! There is a bit of a halo around the perch and bird. Bird approach is to mask these out using quickmask and a soft brush and then work on the BG.
I like the crop on the second post better, Gus, but I'd take it vertical and let the branch wander out of the frame. That butter ball of a bird is too cute! Very nice HA and pose. He looks like he might be a teeny tiny hot on his breast in two places. You might grab that light yellow color and paint over the two bright areas at 15-20% opacity and see if that works.
