As you can see from the first picture, there was some lighting consistency issues in my textures and it didn’t look right at all. I had to re-arrange my rendering setup to get things to look closer to the collar.
The shape works well for the wrists and ankles, so that’s one less thing to worry about.
The last picture is with and without the hoops. (The version with the hoops is darker because of the corrosion buildup around the edges of the part)
