When ever you "slip into this posture because you don't pay attention" what is happening is that you delegate the control over your mechanism to your subconscious mind. To your feelings. You end up in this position because it "feels right".
From a bio mechanical perspective, this isn't satisfactory. You are hurting yourself, constricting breathing, circulation, digestion. You aren't using your mechanism correctly.
What we see is the very usual pattern many times repeated.
Feet apart at the front. The out steps of your feet (blue lines) should be parallel.
Knees slightly released forwards.
Pelvis isn't looking too bad from this angle (in terms of rotation), but is certainly shifted far too forwards horizontally. The waist height blue spot (iliac) should be on the green line.
Upper torso (ribcage) is rotated backwards at the top (look at the slant of the sternum - yellow) in relation to the middle and lower torso. You can see how it creates the arch in the lowerback (red curve) and creates the "protruding abdomen" - that's actually a term we use. Your abdominal muscles are completely out of action.
Arms should be also further forward, but aren't retracted as much as is normally seen.
You however really jam your head backwards, in order to sustain the equilibrium.
You are habitually placing your right foot ahead of the left. Consistently on each image. That set's of a spiral of twists through out the body.
You can see the lean of your weight to the left side / leg.
You are retracing your right arm further back then your left. That makes it also "higher".
All pretty standard distortions, easily fixable with learning to consciously coordinate each and every part of your mechanism in a way that is more advantageous from mechanical perspective.
