See, this would be an incredibly sad and heartfelt moment if anyone even cared about the guy. But since we don't know who he is, or his story, the entire moment is just sort of lost on the readers. A few flashback panels don't really accomplish much, but I can see what you were trying to do.

And as I said in the ABR thread, your art has improved insanely. I'm actually quite surprised that some basic tips helped improve your art this much.
[ego] But I suppose I'm just that awesome. [/ego]

Some criticism though, in panel 3, the katana has blood on it, yet it vanishes completely after that. In panel 9, the panel cuts into the top of the speech bubble. I also feel that you overused the bowed head/crying pose for green-robed guy.

I personally would have had him kneeling down next to white-cape guy in panel 7 and then getting back up at panel 9 or so. As it is he just ran there to stand next to him.

But those are just minor details, all in all you're doing good.
