OK I have had a play and this is how I would do it, you can rotate some of the bones to see what happens. There are some hints about materials and lighting as well, not hard and fast rules, but some ideas.
Here is your revised blend file, I have left your work in it, although I have moved your armature to a different layer to the mesh - this is good practice!

Take a close look at the mesh and the Modifiers I have added, and the number of vertices in my mesh. :yes:
You had deleted the lamp, you had no background - it will never render. I have put this right. Please take a REAL CLOSE look at the armature (Bone rotation type, transform locks, parenting, etc, etc) and the weights. Select the body, go to Weight Paint mode and choose each bone in the Vertex Groups section. You will see that basis for a good weight painting - it needs more work, but that’s your job now!
I know you may feel a little battered after my posts (I hope you find them constructive). Blender’s learning curve is very steep in the early days, but we are here to help.
