These Walt Disney's Signature Collections, including this one is very detailed and unique, yet looks so simple and uncomplicated.
The lines and sketches are flawless, they look exactly like the sketches on Disney's art books or official concept art gallery. I couldn't spot any differences when comparing them with the ones from the studio itself. You adapted Disney's style perfectly.
The layout of each Walt Disney's Signature Collection are carefully arranged,
A thin line as a border, some part of the sketch sticking out, a symbol which represents the theme of the movie (snowflake), title on the top, and quotes below the sketch.
