Is that supposed to be Cesare or Van Kleiss? The one on the left could certainly be a young Cesare but I'm not sure about the one on the right. I'm pretty sure I'm seeing red in the right picture's eyes, and those are definately gray streaks over his temple. Right where Van Kleiss's gray/white streaks are. That and Van Kleiss is pale whereas Cesare is not, and it seems about Van Kleiss's skin tone.
Other than uncertain identity, I love it ^_^. Both sides are very nice. The right side is a bit more complex detail-wise than the left. Symbolically makes me think about how things are so simple when we're children and grow more and more complicated as we age.
