Help needed to fix a model glitchy shoulders

[i2Bros]

I'm working on the first TCW Ashoka Tano conversion in history of modding but I've soon realized I suck at enveloping models. My msh shoulders are weird, so I need somebody to help me fixing them. Here I leave a screenshot, an .exp file for exporting, a badly enveloped msh, the obj file for the model. People, you are my only hope.

HA!!I have the same model rigged and i have the same problem with the shoulders.To be honest you cannot fix that unless you remake the skeleton with the bones to fit her shape since Ahsoka body is very skinny.However if you remake her skeleton this mean you will need to make and new animatons for her and that is something complex.The only solution is put her head on some other body model that is not so skinny.This will happen always when you use skinny models.
