I am having a few problems with your move. Mainly your body movements and your actions. You are grabbing my left with your right? How does your left hand pull my arm in? You are going for a leg sweep from an awkward position which I am having trouble visualizing.
Also the awkward position you are in leaves you open to a very quick, nasty counter. Why didn't you just avoid the upper and reset the fight?
A side note. I never said he was left hand dominate. I just said I was fighting southpaw.
