Nice progress, Janice!
Parting the silks can be trickier sometimes and easy other times. You can try to grab a smaller amount of fabric, or just the edge, pull from there and then continue to find the split. Your entry into fish pose is very flowy great work on that! For the invert before hallelujah, the wrap was probably higher on your back than usual- likely that why the invert struggle. Looks like your legs straightened a bit before the last “tuck through” on the drop. When diving through- keep knees bent to keep forward motion going.
