Welcome to the forums Danny! So happy you decided to join in the fun!
You have a great looking guy there! Are you going to cover that with papermache' for a hollow head or is that the finished head?
For you first marionette I would keep the stringing simple. 11 strings would be a good number.

The weight of the puppet is suspended from the shoulder strings, then you add two to each side of the head, two to the hands, two for the elbows, two on the knees, ending with one on the lower back or butt.
I prefer what is called an airplane control. It looks a lot like a plane with a bunch of wings.

I really need to do some diagrams of a basic controller. Until then as a reference let's use an even simpler control that is often found on children's marionettes.

This kind of gives you an idea. The differences in an 11 string control would be this. First on the front/top of the control you would have another cross bar that is detachable that you would be used for the knees/legs. Then behind that is the hand bar that is actually a run through (see image below) for the hands. It is a static bar and is glued and nailed to the control. Next in line is a control bar for for the head much like you see here. Below that hanging from a cord is a cross bar that is for the shoulders. right behind that is a hole in the main control much like the one seen in the photo for the mouth but it is used for shoulder strings. Then on the back is the hole for the butt string. That is just a general overview of what is needed for the strings. Like I said there are other types of controllers but since I don't use them, I'll leave it to others if they want to explain what they use. It might be worth your time to take a trip to the library and see what they have in the way of books on the subject. I'll try to get some diagrams made up that explain this better but it may take me some time. One last thing. Sometimes I add one more string. It is a nose string. This gets tied off to the front of the controller. I normally put a small screw at at the front for this. That allows you to help balance the head if your puppet has a large nose. Actually even if your puppet isn't nose heavy I like it because it allows the puppet to look up as something or nod.
