The Violet Rebels

Kyra, Rowan, Phoenix, and Asher are part of a prophecy about children with violet eyes that will end the rebellion that is currently taking place. However, although they are rebels, the royalty is winning. When the four prophecy children hear their tutors talking about going on a mission to kidnap the king's daughter and blackmail him into surrendering, they decide to go instead. However, their journey will be far from easy...
Can anybody draw a cover? This eye I very sloppily drew might look nice(maybe), but it's getting boring lol
