Holy Mandarin Duck Batman! I've never seen one of these in person. What a beautiful duck and beautifully captured! They all are beautiful but, that Mandarin is just drop dead gorgeous!
The Mandarin portrait is my favourite.....very detailed, well exposed and with convincing colours.
This is obviously a matter of personal preference, but I think a warmer yellow-brown-green family of colours would work better for its background than blue.
Yes, the colours, exposure, framing and wing attitude of the duck IF is also very nice.
