Beautiful colours, and face. I really think that you got problems with the white balance when taking the picture, have a google search about it. Photoshop and other programs solve it quite right most of the time, edit the pic with it and click auto-colour and that maybe solves the problem.
On the painting I like a lot the subtle flowers of her sleeves, the sheer on her leg (ace!!) and the little fishes and plants at the little pond. Wood looks awesome too.
