2+ years ago was the last time I did a make over of my everyday traveling the Metaverse avatar. Due to multiple people contacting me concerned my shape being copied/distributed I felt compelled to do another make over. Obviously if you change the shape of the ears, it's now "your" original shape, LOL. But the similarities were close enough that I felt uncomfortable with it. The above is one of the many NPCs I've created and used for modeling purposes, and NPC dancers.

I have retired my Catya head: https://gyazo.com/1a0b21469464af37483467e6ea1e2892

There are creators in SL who sell shapes for different heads on MP. You can edit the appearance and copy the numbers on the sliders and use them on your OS avatar. Some full perm shapes can be exported via .XML using regular old firestorm. No copy botting required. Save the file to your computer, and import it on OS. I always suggest tweaking any shape to suit your personality and taste. There are youtube tutorials to show you how to do this.

There are so many free heads out there to play with, don't be limited by what comes in the box. (^_^)
