Lovely santhanu, good to see you here bro, Nice colours, details and BG, As HB mentioned wished for a better Ha and I would have place the bird a little to the top of the frame...
Beautiful bird and a lovely background - I really like the purple 'spots'. I wish for a better head angle, and think the top of hte head could be selectively sharpened a bit.
Good looking KF, and it looks like you got it in a nice open area. HA is the first thing that comes to mind...do you have another frame where it is looking more towards us? I also find the blunt ending the perch unfortunate. A small crop at top and right would help with the comp IMO. I'm finding some of the OOF flowers distracting - specifically the whitish one behind the bill - if this guy would allow it, physically moving right just enough to place it away from the face would have been great.
Very nice, pose perch, bkgd. The bird ends up being sort of small at web sizes to really see well, I might have cropped a bit tighter to make the bird appear bigger so that the detail would be visible.
