Another one of these quickly thrown together PMV's I do

So yeah, that Nightmare PMV that I did ages ago i finally got around to uploading, and then forgot to write about it on here. So here it is. Any feedback would be much appreciated. This one is of Nightmare Moon, with the song Nightmare by Avenged Sevenfold.
