To me, what throws the first three off is the awkwardness of the legs and arms. In numbers one and two, you have the left leg coming forward while the left arm is extended which looks awkward. It's the same with number three, except it's the right arm and leg. Maybe look at rotating number three's arm down 90 degrees. For the first two, have you tried positioning them as if they're landing from a boost instead of running forward. It might give the squad a more dynamic look.
