why is it doing this

Okay I made a women with the joan of ark tutorial.

I used ottos tutorial to make bones for my model.

I made the bones fit with the body so they cannot be seen inlees in x-ray or
the veiw with the z button.

the problem is that parts of the model don’t move like on the picture below.

how can I fix this without seeing balls sticking out on the fingers and arms.

Are you using Envelopes or Vertex Groups (or both)?

If youre using envelopes (and if not just switch them on) then select the bones that are giving trouble in Pose mode and Alt-S to scale the area of influence a little bigger.
