Great perch, nice pose and good job handeling what looks like harsh light. The BG is excellent. Would maybe crop a bit of the left. Otherwise pretty much excellent!
Yes, would crop off some of that dead space and evict the left most bit of flower at the bottom. Beautiful pose and colors, nice and sharp and a nice background that dosen't overpower the bird.
I like the leaning pose, and would leave the space as is. Cool BG. I agree to remove the lower flowers, and would maybe cut back on the sharpening a touch.
