Left one would have been a nightmare to rig. Probably wouldn't have worked as a rig either, kinda like Irys.
Not sure why they canned the right one.
In case you're too much of a newfag to know. They reworked the designs into Lui and Chloe.
You can literally overlay Lui over the left design and the silhouette will match 100%. The parts of Chloe that were retained are obvious.
