When working this final week consider the following:
1) Use of the site/space
2) Aural/Visual/Textual/Physical elements
3) Use of levels, topography, shape, repetition, tempo
4) What does the audience feel/learn/take away with them?
If every point in #2 and #3 is not included that is fine, just look at these things and consider how they are used in your piece, their balance (or imbalance!) and whether adjusting/adding/taking away one of them will change the meaning or impact.
