Mock: Cover Art Progression - Elsa (Frozen)

This is the initial sketch which I used for Elsa. I Wanted to create a sense of movement and elegance, so I used a pose from the animation sequence of her solo "Let it go", possibly one of the most iconic movie songs in film history.

Using an oil brush preset, I painted in the basic shape of her face and hand. I wanted this cover to contrast from the others in the sense that it looked less refined and more like the storyboard designs.
To achieve this, I kept every other detail to a minimum by creating basic shadows on another layer and lowering the transparency. 

On another layer, I added basic highlights to Elsa, and on another layer set to an Overlay setting, I added her makeup. 

I refined the details on her face and hand using an oil brush preset.
I like the contrast the painted features have against the sketchy design.

This is the finished piece. I quite like the contrast of the paint and sketch, but as a whole I'm not sure if I find it particularly aesthetically pleasing.

To make the piece look more interesting, I added in sketches of other main characters in the background. This makes the piece look like it was torn from the sketchbook of the original designers. 

I'm not sure if I will use this in my product, but I like the contrast is has from the other two cover art designs.
