Some of it sounds similar. The Rising and Sideward elbow strike, from the name, sounds like the elbows Up and Cross I use. Dropping elbow, that's an easy one to connect with, so seems the backwards elbow strike.
Roundhouse elbow and downward sweep, I can't picture. In the latter, are you talking about sweeping with a knife hand strike, rather than with your leg?
And the spear hand thrust, I imagine that's just an open hand version of the punch thrusts, or so it sounds...just with the fingers pointing straight ahead instead of a closed fist.
Am I close?
