Your core engagement was excellent. Your lower back remained flat and neutral for the duration of the hold, indicating strong abdominal bracing.
Your shoulders were consistently positioned slightly behind your elbows. This creates a less stable base and can put extra stress on the shoulder joints.
Your upper back appeared flat and stable, suggesting good engagement to prevent your chest from sagging, though a bit more push towards the ceiling would be ideal.
Throughout the hold, your gaze was directed forward, causing your neck to be in a slightly extended position rather than aligned neutrally with your spine.
