I just adore this. Too many times people draw Flitwick as a sort of cute cartoon, and I love that you've made him a genuine adult here, with a wise face befitting the head of Ravenclaw. His blue robes are perfect both for his house and to foreground him at the bright bringer of Christmas cheer. As always, the details are great: the crisp cuffs and cufflink, the robe pleats, the way the light shines on the red ribbons, the cheery explosion of magic, the beautifully-drawn individual pine needles. Outstanding.
