Looking for some mesh assistance

So, I'm converting a mesh from dragon age inquisition to sims 4. All is going well but it involves fingers and I just can't seem to get them in the right spots. Is there anyone out there, good at posing meshes that is willing to put my hands where they should be?

In case there is here is my blender file: drive.google.com/open?id=1WsYXH8qKRmysySahuxyshzsJFNNEZ5ov
