This is a fine concept and its execution shows poise as well as a fine imagination. The detail is very decent and fully competent, with shimmers in the wood and magical colouration in the flowers. The whole thing looks three dimensional and although you are lacking convincing shadows at the base of the tree you have implemented them well in the torso and the tree tops. The background also empowers the image's purpose as well as adding a fresh colour change.
The bright turquoise seems to conflict with the dark contrasted foreground too much though; I would have liked to have seen a slightly darker and greener treetop. Also some of the flowers are black and ugly which blemishes the earthy look.
Still this is a masterpiece and I love it. Your ideas spill into something magnificent.
