Here's a custom I'm very proud of: Tombstone!
The hardest thing when planning this figure was the head. I had already chosen a wrestler body to use, because I wanted him to be big and intimidating, but the head?
I had a [BA cast] head of ML5 Sabretooth and noticed that it's face was close enough, so I cut off the lower jaw and fixed it so I could close the mouth. I gave him a pair of ears from another wrestler, and sculpted a nose and hair.
It still didn't look right, so I re-did some things and sculpted a larger shin, which Tombstone doesn't actually have, but it looked much better.
I sculpted those things on his arms and the collar, and after I started painting him, I remembered I had to sculpt a belt and details on the gloves too (which is why those things aren't on the WIP picture)
Painted grey base with white drybrush for the skin. It was fun.

And that's it! I think it turned out great and I'm really happy with it, though I don't think the pictures really make it justice, but I hope you still like it!
