Wow, this is a very well-done drawing. Slight suggesting, and this only matters if you really want to nitpick: Bellatrix's dress probably wouldn't show off too much of her uh, "goods". Lupin and Serius both had facial hair. (Serius had a full out beard the same color as his hair. Lupin sported a thin 'stache.) And Ginny could have done with a slight age increase, but other than that, there's no room to complain as most of the characters look kickass.
