The pause is lacking. Until you correct that and the hip posture it is good that you don't the head farther back and reach back farther. When you fix those issues that is the next thing which will push you up a distance plateau or two. During the x step tighten up the stomach and lower back muscles some increasing in stiffness every time you tilt at the hips until you don't. Then you know the minimum tightness level needed for consistency.
The biggest thing will probably be planting the final step 6-10" to the right where it is now. I'd try that first before adding muscle tension in the core.
