Sibling Rivalry

Bout time my lazy butt posted something! XD Anyhow, I got around to sketching this on Friday, and picked it up from where I left off! I've always admired Leo and Raph's tight bond, and thought it was about time I created some art to visualize it.  This happens to be the last scene of my Fan Fiction, Double-Crossed {Sneak peek into what may happen!} Leo has joined Shredder's ranks to gather information of what the villain may be plotting against his family, and when Lockjaw, Shredder's mutant pawn, orders an attack on the lair, Raph finally finds out his brother really has betrayed them, or so he thinks. Is Leo's intentions to keep his family safe, or has he really gone bad?
