I guess there is no relation between the anime and its official art in Puella Magi Madoka Magica. :(
Oh no. There is. There very much is. Homura is wearing one of Madoka's hair ribbons, and Madoka only has one. Before leaving for the new world, Homura was given a hair ribbon by Madoka, to remember her by. The two are at kyuudo practice. In the final timeline, both of them use bows to combat evil.
