It doesn't look worse to me, but I'm still very wary of those exposed bones - they're effectively an open 'wound' as there's no way for the bone to seal itself off. It could be one of two things - it could be normal changes with healing, as there's often redness, swelling, and pain with a wound regardless of infection (the redness/swelling/pain is from the body sending more blood to the area for healing), or it could be the beginning signs of infection. The yellow may be healing bruising. Since she's walking and acting normally, I'd just keep a closer eye on her, but it might be a good time to look into vets in the area.
