I finally got to work on making a regular sized Sugar Belle in the Equestria Girls style.
Used many body parts from EQG bases from GihhBloonde and MapleB on deviantART to make her body while I made the dress and hair with my old Sugar Belle images as reference for her height and hair. Now the cupcake on her dress was warped with this app I used called Body Plastic Surgery so I could place it down the bottom of her dress which was curved. Since her ponytail wasn't blocked by her arms like her fat designs, I had to make the full thing, but, I didn't wanna make it too long.

This is my redo of the design. The only difference is the ponytail.
After looking at the original Sugar Belle from the normal MLP:FIM universe, I worked on the ponytail to match it with her pony counterpart.
