Loki became my second test subject as a custom My Little Pony. I made him for ~aREDenigma as a late birthday / christmas / being awesome present. She's absolutely loves Loki and so I just had to! That and the Avengers movie is coming out soon, so making a Loki got me in the mindset. As my second custom My Little Pony, I learned a lot but still had fun!
I figured Loki would be an Alicorn of Trickery! Being a god and all, I had no qualms making him an Alicorn. His two toned eyes show through as he uses his frost giant magic. And his cutie mark is a serpent dripping venom.
I really enjoyed making this pony! Especially Loki's helmet. Though he does have a small habit of faceplanting into the dirt. I also couldn't believe how soft his tail came out!
might I ask what clay? I have a friend who, this Christmas, wants something dealing with Loki, mlp, of dalmatians, so I am going to make a spotted white poni with a loki helmet.
That clay is Apoxie Clay. It air dries, but was kind of hard to work with. I now use Sculpy, and just back it to harden it. Good luck making your pony for your friend!
