The neck of the normal male ebony armor model lools a bit messy and flesh shows through, so I've tried to fix it.

This mod also improves the neckline, among other things, so you could try that instead.

I'm no expert at this, just deleted a component of the mesh and it looks better now to my eye.

Should work with retextures but will overwrite any other remodelling of the male ebony armor cuirass.
