This piece is absolutely stunning !
You did an excellent job combining the various elements into that vivid atmosphere that claims spring.
The choice of both forest as a background, and mostly light animals gives a feeling of life, lightness, and the joy of a reborn nature. The deer, on the other hand, integrates seamlessly as the woman's companion. It just has to be there.
The dominant golden yellow tones evocate the rising sun, while the use of other colours, in particular the blue butterfly and pink flowers, add a exquisite touch of contrast compared to a simple camaïeu.
The light coming from behind the model makes her kind of glow, and emphasizes her as being the central element of the picture. It's bright enough to envelope the whole picture though slowly fading away, yet soft enough to be warming without being aggressive.
In one word, this piece is a real masterpiece.
