Aliens xenomorph inner jaw custom 2 sizes

Aliens xenomorph inner jaw custom 2 sizes.  The 140mm is shorter so it looks like the inner jaw is retracted in the xeno's mouth.  The other is the full length but also customized.  

In the photos, my version is the white PLA and the gray one is the version from Jace1969 which is really good.  I felt it needed to look more aggressive and sneer-like.  The angles are much harder, I've added the corrugated tube looking areas and sharpened the teeth and melded into the gum line a little more.
