Hey mate, so what we have here are some very common patterns of mis-use of the mechanism.
As usual, we start with feet. Feet aren't placed properly for standing. Your toes are fanning out wider than your heels. Ideally, we would want the outsteps (the blue lines on the posterior view) to be parallel.
You also have the habitual tendency to place your left foot forward to the right, which then "ripples" through out the mechanism and causes the left / right imbalances. I'll return to this later.
On the right side view, you see blue markers. Ankles, knees, iliacs (anterior superior iliac spine), bottom and top sternum. All these markers would need to be on the green plumb line in order to re-gain proper functioning of the mechanism.
Lets talk about the most important part of your body - your torso. That is your pelvis (lower torso), your ribcage (upper torso) and the middle torso, which is inbetween and consists of your spine and abdominal cavity.
On the left side view, I have marked the 3 parts of your torso as blocks - blue, purple and yellow. Your current pattern of movement is to rotate the pelvis forward and down as suggested by the arrow. We could even label this as a anti-clockwise rotation when we are using the left side image.
There is another rotation present - that is your ribcage (yellow rectangle). This is exactly the opposite rotation to the pelvic one, this time, we could label it clockwise rotation. It's easily visible, as your sternum is sloping backward at the top, pushing the bottom of the sternum forward.
Now, when you have two fairly rigid objects (plevis and ribcage) and you rotate each of the object in an opposing direction, you will get a shape of the spine just like what you see - it's arched / bent in the lowerback area as highlighted by the red curve.
This curve means one thing - you are shortening your torso and it's not doing any good for you. Your breating, circulation and digestion are all affected by the shape of the torso. If you look carefully at the shape of the back curve, you will see that your abdomen is kind of copying it at the front. We call it a protruding abdomen and it will disappear if you organise the shape of your spine the way it should be - straight in the lowerback.
To change this situation, you would want to start rotating the pelvis (as well as the ribcage) in exactly the reverse way to what is happening now. The reversal of the rotations will in turn straighten the curve in the back.
You are also retracting your arms (the entire arm mechanism, that is arms + shoulders + clavicles, shoulderblades are too close to each other). And of course you are retracting the head back as well.
When you look at the front / back views you will see left and right assymetries. Again, we should be symetrical.
Your left foot goes ahead of the right, so does your left knee and left hip. Pushing the "bottom" side of your body forward on the left means that you have to counterbalance it somewhere (in order to maintain equilibrium). This counterbalance is done by pulling the left arm backwards more than the right (your left scapula protruding more then the right - that means it's being retracted more back in relation to the torso).
In my opinion, all of the above can be resolved by learning to move the parts of your body in a different way. In a way that will result in a better mechanical functioning of the whole system.
