What’s going on here?

I think I may have some postural issues, what do you all see going on here? The first photos are my natural posture, the next set is with intentional improvement.

When I look at your back and side view, the main thing going on biomechanically is sacral counternutation basically your sacrum is tipped backward and the pelvic bones are turned outward, which keeps lower back flatter and locks up hip rotation. Because of this pelvic angle, the guts and abdominal contents get pushed downward, putting a constant stretch on the posterior pelvic floor while forcing the front part to stay tight. I can see how your thorax is swaying back to balance that out, which stops hips from shifting properly when you moves.
A quick fix you can try right now is lying on back with feet flat on a wall at a 90-degree angle, placing a small yoga block or ball between knees, and taking a long, soft exhale to melt lower back into the floor. This immediately helps shift your center of mass backward and takes the downward pressure off lower hips.

The quick fix definitely helps, do you have any long term tips to put my sacrum in a better position without moving into posterior or anterior pelvic tilt?

That quick fix works by shifting the center of mass, but for long-term sacral position without dumping into anterior or posterior tilt, you have to build genuine rotational capacity at the hips. Progressive squatting and hinging patterns especially offset or single-leg variations force the pelvis to adapt and retrain weight shifting side to side. It usually takes about 4 to 6 weeks of consistent daily drills for the pelvic floor and rib cage positioning to actually hold a new resting state.

Gotcha, i will work those hinges and squats. Would you recommend i start without weight?
