There is a single dark green pixel low on the branch. Other than that, you've achieved what you set out to do and it looks lovely.
Anawhooo! those colors look HOW. Much doge- much masterfulness - love it!
Oh yes that was the one exception, I decided that at the very beginning.
I think this piece would definitely benefit from an opaque background. Looks a lot better in the preview, compared to my background.
Super beautiful piece, though.
Except for the eye highlight, right? Or am I getting anything wrong?
Awesome work, never the less!!! 
That must have been a very happy mum.
