Create a highly detailed and realistic full-body image of a character with the following features: The character has sky blue skin and icy blue hair styled in an elegant updo with loose waves falling around the shoulders. They exhibit a serene and confident expression. The attire is a blend of fantasy and futuristic fashion, featuring a long, flowing gown with a subtle sheen, suggesting it is made of a silky material. Over the gown, the character wears a translucent, crystalline cape or wings that add to their otherworldly aura. They are holding a staff with a glowing geometric crystal on top, signifying magical power. The character's presence is regal, with a poised stance that exudes a sense of calm authority. The background should be a soft gradient that complements the ethereal and majestic theme of the character.
