Well this gives off that ethereal feeling and element for sure, I do love the way the girl looks up as if she is looking to god or heavens or something bigger than her. I love the braid in her hair off to the side and the shading you used with blacks and whites works really well here. I do like the subtle background with bursts of speckles in the black background as if she is beaming or full of magic. I do think this could use coloring, or a version in color, just to see what you can do there, as I always love to see things in different perspectives.
~~THINGS TO IMPROVE ON~~
Try doing this with some colors next time but good job overall
