Rinnegan evolution

EDIT: THIS THEORY WAS PROVEN FALSE. SECOND DŌJUTSU IS CONSIDERED A MANGEKYŌ SHARINGAN AND SO THERE'S NO THIRD DŌJUTSU. HERE'S THE CORRECT VERSION.

My concept of transformation of Rinnegan into Sharingan. It features three Dōjutsu shown in the series ('Rinnegan', 'Rinnegan's descendant' and 'Sharingan') and one transitional form. Maybe someday it will be shown in the show.

P.S. I want to make animated version sometime in the future.
