The new Mareana Sweetie (Updated SFM custom model)

So yeah, this is the new custom private model of my mare Mareana Sweetie, it took a lot of work for my friend to do it and the result it's amazing. Here I left the things that were changed on her.

- Fixed a problem with the texture of her ears that could make some errors during the rendering, for example a different colour compared to the head.
- Updated the mane with a new custom one made in Blender to remove the "Vinyl Scratch's stock mane" and have something similar but more unique.
