Still skinning the head

My file crashed on me but luckily i saved the file at the right time so nothing terrible happened and I'm still skinning the head.

Skinning the head

I've skinned his right shoulder and wrist and now skinning his head, going fine but there is this grey part that will not go away, it's really bugging me cause it stays in place when i move his head so it looks like some weird worm or something coming out of is skull every time he moves so......working on that right now.....T_T

Fixing the shoulder

Started the skinning but something weird happened and discovered that I was a bigger idiot and didn't merge his vertices together so there were a few holes in his armpits and a vertex that wasn't even joined to anything, had to cut out holes so it could actually be joined and fixed the rest so its all good.

Fixing his mouth

This where I had a problem making his mouth open so I could animate him talking, the end blend shape wasn't affecting the dummy, I took a closer look and found out that his teeth were stuck together.

Very embarrassing and very stupid on my behalf, so I tried to fix it with some help form others and the his mouth turned out like this..

Did this with both the dummy and master and made duplicates buuuuuuuuuut.....they don't work when the blend shapes are made so i started the blend shapes again. So now his mouth doesn't open but i worked with it.
