Gaps when rigging model

I’m trying to rig a model of Zero Suit Samus from SSBB and, although there is still a lot to be done, as you can see with the current pose, there are gaps in the model that need to be filled. How could I fill these gaps, since in edit mode, it just brings me to the original pose. Any suggestion would be helpful.

Thanks in advanced.


Nice character!

You can apply the armature modifier in edit mode by clicking the right button in the armature modifier next to the header. A circle will appear, click that too and the character will be editable in the posed position.
