Specialty techniques or principles or ways of expressing a MA, is what makes TCMA different than others and what MAY give a person the edge.
Now, that is NOT to say that TCMA has things that other MA don't and as an example lets look at the PE fist ( Phoenix-eye):
Some TCMA have it and some prioritize it (SPM, Pak Mei, Dragon shape boxing, etc) BUT so do many Karate systems ( Uechi-ryu, Goju, etc).
What makes a system "special" is how it is used and, at times, how it is developed.
But, to answer your question:
I don't have A style persay, other than my own
But what makes what I do unique (and to not give out the uber-deadly secrets of course):
Iron Hand and Iron Body
PE fist not only in the TCMA BUT in a western way too.
"In-your-face" kicking
"blind side" angling.
And more..
Now, that these things may also be found in other systems is quite correct and perfectly find because, well, they work.

Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
