Poses in Blender

I have a model of Mario that needs to be placed in positions. I have the base model, and each section that makes up the model moveable, not a closed mesh model. I have a series of poses taken from a sprite sheet of an old Mario game that the model needs to be placed in the same position. I have the blender files and the images to copy the poses of. Some of the sections of the Mario need to have more vertices added to them to close the shapes, as the sections were split from a model to create the sections (Top left arm) has missing vertices where it was removed from the body. This will need to be closed up and finished to complete the shape, as moving the sections to match the sprite positions exposes the missing vertices and looks unclean. I have done the head, and the arm holes on the body, the areas where the feet have been separated are still needing to be finished, as well as the hands and the arms. There are a total of 8 unique positions / poses. Some of the poses need to be mirrored so that the same pose is facing the opposite way, (facing left), or facing right. depending on the pose. This brings the positions up to 14, (2 of the poses are front facing). I have the poses but it wont let me upload more than 3 images. I have completed 1 pose, matched to the example pose. I have done this from the perspective of fixed -Y axis in the workspace. The second screen shot from blender shows the missing vertices in the sections that make up the model. These gaps would need to be closed and in keeping with the current vertices look and shape, (not just flattened to close the gaps)
