Have more Luna.
Well kind of Luna. I like to have her with Nightmare Moon qualities in my head-canon.
Like she accepts her darker side and goes with those emotions more, when she needs to; rather than repressing them till she explodes. Xp

Doing so means darker coat color, semi-slit eyes, fangs etc.etc.
Also her mane was so fun to do like this. X3

And now goodnight; I have to work in like 5-6 hours or something
