That big thick circle you put on it makes it kind of hard to see, but it looks fine to me anyways, I don't see a problem here. Maybe I'm missing something and I'm no expert on anatomy, but looks pretty normal to me.

It appears that the shoulder is attached directly to the neck. Lower it somewhat.

 

 

 

The shoulder is directly connected to the back. It is a separate entity to the back, so I suggest you limit the connection to the armpit only.

Google image search for proportion. ;P
