Original Description:
 
I wanted to do something that was more on the theme of nightmare night~ So I made another thing for this art event~ Twilight was able to convince fluttershy to go out on nightmare night, and not only that, but she also manage to make her wear a Madotsuki cosplay too~ Twilight is going as an average nerdy girl, she’s surprised at how much this outif looks like something that Moondancer would wear!
 
Sugarcube Corner and the ponyville buildings behind were made by discopears, and the models can be found here
 
Fluttershy and Twilight are from the ReVAmped SFW Ponies pack which can be found here
 
Everything else was made by me.
