Holding Punch+Kick, Free+Punch, or Free+Kick during the replay will allow
you to select your win pose.
Controlling camera during win pose
After winning a bout in either Single or Time Attack mode, hold down Punch
after the replay finishes. You will then be able to move the camera around
using the stick. Keep holding down Punch while moving the stick. Free
will zoom into your fighter, while Kick will zoom out. The only
limitations to camera movement are that you cannot look directly above or
below your fighter.
