The first thing that I noticed about this beautiful work was the way the background is so well blended. The rocks, mist, water and clouds all join together seamlessly. The colours are blended very well too - the blue is beautiful and very atmospheric. The only major problem that I see is the lighting on the model. Her left side especially is bright, almost as if it was lit by sunlight, and some of this brightness is also visible on and under her right arm. I think this lighting contrasts too much with the darkness in other areas of the image, especially the rock and sky on the left. Perhaps if the left hand side of the picture was lighter then the brightness of the model (and also the tree branches) would look more realistic. Other than that, though, it is a beautifully manipulated picture and I love the song you've based it on. Well done
