Personal Skin Help

I don’t know if I post this here but whatever…

There are only 2 problems I have with my skin and model

  1. The flexes or physics (or however you say it) is bad cause is very stiff.
  2. I put a different type of logo over the one’s that were attached to the model, but it stills shows up.

I would really appreciate some help with this.
