a) you can never have too many Snape icons (he's the little black dress of fandom);
b) it fits in perfectly with one of the main points in my Convention Alley presentation, and will be a good reminder to me that I really need to write that outline and essay;
c) I'm very pleased with the results I'm getting as I'm learning more about text and brushes in Photoshop; and
d) I thought it was about time somebody used hymn lyrics on an icon, and the quote here reflects what I believe about myself, and my own relation to God.
So there you have it.
