I really like thisIt's rare to see Deidara in any real contemplative, sober mood that gives off the air he's in deep thought. I always thought that he was a bit on the zany side because of his radical terrorist background and his manic behavior that delved into his "Art" in a way that was opposite to Sasori. Whereas Sasori was molded by tragedy, Deidara seemed to be psychologically motivated since a young age, given what we know about him. But I like your fan interpretation of him, giving him different shades to his character in the works you've done; which makes since why he looks the way he does in this old sketch of yours. Very nice work ^^
