This is the 100,000 kiriban for . He asked for a picture of Sasuke and Itachi fighting (Sasuke with Sharingan and Itachi with Mangekyou Sharingan).
...this was very challenging, to say the least. I think I spent several hours alone on thumbnail sketches to decide on the poses and composition. I've also never drawn Itachi properly before, and we haven't seen him fight very much so far, so I wasn't entirely sure what to have him doing.
But all up, I'm pretty happy with this; Sasuke turned out pretty much how I wanted him to look and I had a lot of fun with the lighting style.
*EDIT* People pointed out that Sasuke looked a little crosseyed, so I adjusted the eyes a little.
