Looks Cassie

As usual, genital textures were broken. They're better now.

Mainly removing dependencies which were free content morph packs not available on the hub; morphs are now bundled with the look. Also some minor texture tweaks, and conversion from PNG to JPG where appropriate to reduce file size.

At the suggestion of @SolidVault, I've corrected the issues with Cassie's eyes in the morph. I've also generated a full set of genital textures so that things actually match up properly, and added a couple extra shaping morphs that make her look a little less weird. Finally, there's now a preset in there for her skin, if you feel like using it on another model for some reason. Enjoy!
