Hi Cornell, good to see you making progress Bro
I would say the strapping joining the bell to the shoulder needs to be shorter, they have a tendency to twist otherwise. Also the return edge on the bells can be removed altogether which allows them to sit nicely and is also screen accurate, usually the return edge on the bottom of the biceps is removed also.
I am no expert by any means dude, this is based on the build research i have done.
You will get sound and accurate advise from Scribbler, Smally, Iconoclaster and any of the other armourers on the forum.
Hope this helps
