Not bad, couple things to work on:
1)Hug the knee don't just rest your hand on it, make it a tight clinch
2) During the DA Sweep don't grab his elbow with your left arm, wrap it just under his butt to the far hip to prevent the cartwheel escape.You can use your right hand to control the wrist if you need to.
3)Make sure to iron palm his hip to ensure the completion of the sweep and obtaining twister side control.
4)In Twister Side Control, get your ass on his chest and keep it off the floor.
5) Don't triangle your legs during the calf crush, stomp the foot, otherwise he can counter with a calf crush of his own. Same during the crotch ripper.
6) Also be careful grabbing his foot with your inside (left ) arm, there is a counter arm bar there.
7) There is a huge battle you are bypassing when you put his arm under the head, there are a few set ups (I recommend watching the NEW final 3 steps to the twister Episode of MTS to see how thats now being handled).
Its awesome to see 10p developing in other countries!
