Spike's Nightmare Night Costume(Spikenite)

Well, here it is, just like I promised. I'll be honest, it took me all day to get the idea for this. This took about 5 or 6 hours to complete. It would have been less but an hour of time was conceptualization as I went. At first I wasn't going to put any shadows in here, but I gave it a try and man this looks a hundred times better. I threw in two other characters. You can see Luna quite easily, but there's someone else hiding in there. Who's also ancient. (hint: pumpkin). Since it's October and Halloween is around the corner (or Nightmare Night, if you wish to be relevant to the piece) I went with a costume theme.

P.S. Expect me to do this Nightmare Night/costumed theme for the other ponays. Specific requests would be nice. I already have a Discord costume idea.
P.S.S. I need to get a 3ds so I can play the new pokemon already T_T
