I see a guy teaching credible stuff with little skill.
Eyebrows raise when beginning to strike.
Chin comes up when delivering a strike.
Eyes watch hand movements of opponent.
Hands and arms of opponent are the focus not the body and movement.
Teaching his students to control the arms and hands instead of the body of the opponent.
Mouth opens to inhale when finishing a strike.
Worst of all, after every move he looks around for approval.
Not a pakua person, but martial arts are martial arts and all of these things are signs of an unskilled person who has not had there head knocked in by a credible teacher.
