Private Exchange's : Annual Halloween

I won't pass next to an elf without blinking, so my victim is Eureta. I kinda decided to make a little step on the side with this exchange, but i hope it still qualifies as scary/spooky/cute-spooky. I couldn't think of anything decent for her, and "Caterinas" were currently in my head, so i gave it a shot. I also thought that she might use a company since she was looking so alone on my first sketch, so I added her a collegue - Kellathua. I guess that those two aldies might actually like each other considering Eureta's bio ;) Besides i had to many ideas for costumes to put it on one model. So i still hope this little crossover is allright.
