Green Heron Photo Rejected Due to Quality Issues

Thanks Ricky!  The color of the bird's body is correct.  I do not know how the "green" got into the bird's name...but as with a number of animal/bird names, they are not always a true description of the actual color.  

In any case, your observations on of the detail and tone curve are well received...I will work with that.  Thanks for your input!

Abambo...no cutout or movement of the bird in this photo.  I did do some work on the palm frond curvature lower left, but nothing on the bird.  

You trained me well on cutouts on PNG files in some of my past inquiries on rejections.  And I have had few problems in that area since.  Thanks for your input.

The photo was cropped to 3037 x 5504, from 8256 x 5504.

I posted in RGB...my Nikon ZII has only 2 options in the Menu...sRGB and Adobe RGB.  I shot in sRGB...although Bridge shows only RGB in Metadata.  

I did post a similar photo, taken at the same time, cropped to a larger size (3429 x 2286), which was accepted.  Keywords, on the accepted file, did not include Nikon or camera type...that may have been a deciding factor.  Otherwise the accepted photo was processed in similar fashion.

Noise was processed in Camera Raw, Detail, Noise Reduction.

Your comments are very much appreciated.  The keywords can be easily resolved.  If anything I state above is of additional concern, your input would be well received.
