Inverted crucifix

I can invert from my knees, I can do pole crunches and there is no kicking involved when I go up so I know I am strong enough to invert and doing it right but for whatever reason once I am up I cannot figure out what I do to get into crucifix?? I got it ONCE and my boot zipper came undone and I fell down and I have not been able to get it again. so I am including a picture since my vid is broken and I cant film 🙁 tell me which arm goes down first and what I do differently with my legs? Thanks in advance
