Like I said, @MIGShinobi, as an artist it's easier to make that inconsistency than you think. It all has to do with what Kishi wanted to be shown in the panel. If he wanted all of the Yata mirror in the panel, he had to make it smaller. To say it's too big a change to be an artist error is kind of arbitrary. It most certainly could be an artist error.

But even if it wasn't an artist error, that's only a change in size. Naruto can change his Rasengan's size. What's stopping him from changing its shape into a sword, a spear, a kunai, or even a shield? The properties of the technique, that's it.

Also, if you think Madara isn't smart, I have no idea what to tell you. He's one of the smartest people in the dang series.
