We’re out of season for that now, but I’ll be uploading a bunch of photos of this year’s Nightmare Night in “Legends of Equestria” now, since I just got done with sorting them out.  
In total, I made over 300 pictures during Nightmare Night and the event, many of them in the bat pony costume you could get for doing the limited-time Nightmare Night quest “Costume of the Night” and in the rest of the Nightmare Night costumes. I’ll upload the best of those here.
 

 
First off, Scootaloo in the aforementioned bat pony costume in Celestia’s and Luna’s old castle in the Everfree, epically posing in front of the moon and night sky.
