Comments:
- Don't let the model walk from off screen to on screen (left edge to right edge)
- If transitioning from walking to stand still maybe use 'Crossfade'
- If the model walks from left to right, then make him/her appear from right to left.
- Use Final Cut Pro for rough cut, but try to use After Effect for other changes/effects.
- Change the piece so that they are in sync with music
- In the Sun scene (at the end), maybe try darken the areas around it, then fade out altogether.
- Try to avoid black screens.
