Presentation Feedback

Focus on the tempo of the entire piece.
Experiment with slomo to really expose the gestures.
Repetition is fine, especially if the music develops and is associated with certain gestures.
Match certain gestures with musical themes then develop them over time, as in traditional western classical music structure.
Create a dialog between gestures. Use them in conversation with each other simultaneously in the frame.

The use of nostalgic music has a connection to silent movies, especially the honkey tonk piano. Source more sounds from silent movies.
The silent gaps between samples helps to connect musical motives to specific gestures.
Sourcing the music from dance films adds another level of association to movement of the gestures.

Animating the colour of the background over time adds too much information. The reading of the music and the gesture is enough for the viewer.
The background colour works well in a single constant colour.
Black and white has a purity to it but black has a connection to the void.
Dark brown is somehow more viscous, fills the space and defines the boundaries of the frame.
Experiement with coloured gesture lines, off white to soften it, or a lighter version of the background colour.

I have definitely decided to project it. It looks GREAT large.
