This is a beautiful mix of purples and blues and the swirls, the stars and the moon only add to its beauty. But, I wouldn’t be writing this as a critique if I didn’t find something that could be improved. So just let me say that while I love this newest work of yours there are things I felt could have been done better.

The first thing that jumps out at me is the bottom part of her face. While the lower part of the face has more shadows falling on it, both normally and in your stock image, then the rest of the face it is never as dark as the area of the neck under it; it can come close but never gets there. Here, however, you have darkened it to that point.

Another problem I would like to point out is there is no reflected light outlining her chin and bottom edges of her face. Light bounces, if light hits one thing and there is another thing close to it its going to bounce and hit it too. The light in this image is coming from in front of the girl and a little bit above her head. This means that if this were a shot that showed her chest and breasts you would be able to see light hitting there and the light hitting her chest and breasts would bounce up and light the part of her neck that lays under the chin (Which doesn’t really matter here because her head is tilled down so we can’t see that part of her neck.) and it would outline her chin and the bottom edges of her face. And while, yes, the image is only of her face, she has no chest or breasts to speak of that we can see the light would still reflect and outline the bottom part of her face. Other wise it looks like the chin is growing out of the neck…

All of this can be seen if you take a closer look at the original stock image. The reflected light outlining her chin and lower face is there, so is the differences in shadows in the face and neck. And there are even a few more places where reflected light is hitting that I didn’t mention, take a nice long look at the stock image and see how many you can find.
