I am in love with this piece. Why? Mostly because it's a beautiful, magical scene you created for us. But it's also blue, very blue.
My favorite part of this, by far, is how you blended the fairy's dress with the mist. It's a perfect transition.
The light is very strong, but it adds to the scene. However, it seems a little much on the model. For example, the details of her profile seem to have been lost a little, and her torso appears to be fading into the background. If the lighting effects were lowered a bit on her, we'd be able to see more of her. Also, there is an odd spot of shadow underneath her hand that takes away from the flow of this manip. Lastly, the vines that border the piece are a little bright given their distance from the light source; they're just a tad distracting.
I greatly enjoyed taking in every little piece of this manip. It's one where you can easily come up with a story to give it some life (to me she's opening a portal to get ready to travel to another stunning world). You did some great work.
