>>4196351try and get a bit closer to the subject if you can and time your shots slightly better. Im not expecting a miracle with a film camera, but even the post swing for the baseball could have been cool. For the dancer i feel slightly slower shutter speed and try to capture the motion better. Plus like i mentioned the breathing room might work better on the other side
