Orochimaru and the Four-Tails

The Orochimaru versus the Four-Tail Kyuubi Naruto was something I had wanted to do for a long time. It would be a great chance to see some more of the demon's abilities.
Originally, I had wanted Orochimaru to be wielding the Kusanagi sword from the outset, as seen in this early sketch I had done.
I drew this before the introduction of Sai, and I was very impatient to get to the battle.
Please pardon the anatomy mistakes, as this was done very quickly.
