I like the way part of the background is dark and then the is this thick piece of light, as if it were a door opened letting in light. And you even have Deidara and Sasori in the light!!
So, this is one of my favorite Deidara and Sasori pictures. Plus, it looks like they were possibly having an argument because their hands are either balled into fists, or their fingers are partly bent.
Two thumbs up!!
