I adore the expressions! Severus seems to know that he's soooo much more a hottie than Ginny, and she appears to realize it, too!
The rainbow and shining aura should be a real tip-off to Harry that Severus is his one-and-only. I like how the color throws Severus' customary black into relief, making it a clearly classier alternative to Ginny's quite abundant charms (and he matches Harry better, too)! And though I am quite the fan of his sandals, the shoes are mighty flashy!
