Costume Change for protagonist and antagonist

We have decided that we want to use the military uniform for the protagonist rather than the antagonist. This is because the connotations of people in the military are probably more positive when shown in action films. However we will also use other costumes for the protagonist at other times in the trailer, such as a leather jacket and black trousers for the 'running scene'. The reason for this is that we wanted to emulate the style of the costume of "Cloud Strife", the protagonist from the 2005 film "Final Fantasy: Advent Children" because we believe this film to be of a very similar genre and style to ours - action/fantasy.
