Since I am not a premium member, I cannot write an official critique for this art work, so I will post it here. I will say it is a wonderful work of art, however the pose she is in is a very unnatural pose, even for running/jumping. It also may just be the angle you drew her head at but it seems to be a bit too small comparatively to her body. Besides that, it's wonderful, the colors work together beautifully and the shading looks very well done. I would give it a 8.7 out of 10.
Let me just begin with 'Holy shit that's pretty.' I mean, wow. I love the luminous forest as well as the glow behind her, and the folds in her cloak give this a wonderful feeling of movement. The only thing that struck me as odd was that the shines on the end of her hair, and those on the middle seem awkward, they don't really blend in with the rest of the hair. Not to be rude, but it looks like they were almost haphazardly dashed across her hair at the end, without any real attempt to incorporated them into the lighting of the rest of the hair.
