I love it!!! You really want a critique? Seriously? The art is superb! If I had one suggestion it would be to move your framing so your content isn't centered sometimes. Your stuff is already crazy cinematic!!
I just realized something about Agent Orange. The way he kills people and absorbs their identity/soul. It's pretty much the same thing Freddy Krueger does. Except their faces don't appear on Larfleeze's chest.
Where was I? Oh, yeah, anyway, your art really fit with this little back up thing. I hope it wasn't a pain having to draw all those rings. Hope there's more of these in the next Green Lanterns.
