Wow, this is awesome! I love the effect you've chosen for Voldemort, and the contrast to how you show Severus works beautifully. Also - the quality of Severus' hair! You can basically see the oil dripping from it, which may not be the most, y'know, erotic sight, but it is how he appears in canon, so. The angle of Severus' hand is also really, um, cool (god I wish I knew more about art so that I could make my comment sound more educated!), and I love how he tilts up Harry's chin. "Focus, Harry!" indeed.
