Thank you @mitsuki-youko and @patrycja.lerch. Glad you like the wings.
I painted my elf and reindeer piece. Here's the grayscale.
Here are some colors. I wanted to add a blue tint to the background.
I also added a light source with the lantern.
I forgot to add her eye color. And while I was at it, I added some snow in the foreground and background. It looks pretty cool. Holly leads Prancer through the forest as flurries fall from the trees. This is my last piece for the year. I like this so far.
