First of all, I'd like to say that I LOVE THIS MOVIE. I love seeing good art from it since it's so underrated, especially ones that are as detailed as this one.
I love how you captured the mood of this whole scene, with all of the blues and blacks and how you captured Kida. Your style stays real to the character and you can instantly tell that it's her other than the fact that she is not cartoony or anatomically disproportionate. I also love how detailed you are about the Atlantian writing in the background, especially since finding the writing on the internet is pretty hard and learning it even harder.
However, as much as this piece stands out, I find one problem with it: her pose. I love the use of the arms and most of her upper body, but below her sternum is what bugs me. The lower half of her body looks very awkward and stiff. When you watch the scene in the movie, Kida's body is free flowing and completely under the control of the crystal and feels no intention to break free from it. In here, she doesn't look like it at all and, to me, she doesn't look as relaxed as I'd picture her to be.
Of course, this is your interpretation since it's far from what the "Disnola" style looks like, but personally if you wanted to capture the power of this scene in the film, the use of her body language is what I feel to be one of the important parts of interpreting this part of the movie.
Overall, though, it's a stunning piece of work and your use of values is really striking Keep up the great Disney work!
Thanks for the feedback, it is highly appreciated.
As for her body position, i wasn't looking to get 100% exact pose like in the movie.
