Here is what I think about your posture.
From our perspective, this is unsatisfactory use of the postural mechanism. You are seen in a position of "mechanical disadvantage". That's just fancy for the fact that you can think of your body as a machine (system of parts) that operates in the field of gravity. There is a certain biomechanical design that promotes proper functioning of the whole thing. We would call it a position of "mechanical advantage".
What we see:
- Feet improperly placed (outsteps outlined with blue should be parallel).
- Knees and ankles don't look too bad to be honest, although your knees are too close to each other.
- The red curve at your back is your shortening of the torso. Basically, you rotate your upper torso (ribcage) in clockwise direction (leaning back at the top) and you rotate your pelvis in the opposite way (counterclockwise). You do that by lifting your sacrum up and sending your iliacs (anterior superior iliac spine) forward and down.
These two rotations result in the curve in the back (and the protruding abdomen in the front). Your belly muscles are completely out of action. If you would coordinate your mechanism properly, most of your "gut" will disappear. You could half your belly in one lesson. It's just posture related. - The yellow line is your sternum. I'ts slope (front of your ribcage) is paralel to the top part of the red curve at the back. Your ribcage is between these two lines. And it's leaning back.
- The blue and white markers are: (ankles, knees, iliacs, bottom and top sternum). They all should be on that green plumb line that has been adjusted to the verticals on the door behind.
- Shoulders are too high, neck is shortened. On the side view, you see the skin where you shorten the most. On the anterior / posterior view, you can compare the imbalance of the shouldergirdle. The white frame is centered to the green line. Clearly some twists going on there.
- You carry most of your weight on the front of your feet and you tend to lean to your right if i'm not mistaken.
This is very, very common config. It's not good, but it's common. 100% fixable.
