the clever, neat ideas - the My Little Thestral set *snort*, the dueling Chocolate Frog cards, the Embarrassment Charm!
the beautifully paced scenes, not just Draco and Harry having hot, awkward, sniping-the-whole time sex, but the very realistic and amusing scenes with Harry's family.
the plot! Great use of the children (including Izzy!) and the coolest part was how perfectly it wrapped up at the end! Three cheers for your craft, well-executed from top to bottom!
