First off, I enjoyed it.  It was well done, shots were in focus, camera was steady, editing was well-paced, and sound design was appropriate.  The concept was well-executed; I applaud them for creating an experimental dance piece around a soon-to-be-demolished building.  Bravo! 
  
With that being said, I don't consider this to be a short film.  If anything, this is a modern dance video (very well done to be sure).  I feel like the term 'short film' is thrown around way too freely.  Not to diminish SKIN at all, but just because someone shoots a bunch of footage (often unplanned with no thought to a throughline or story arc) and edits it together (often with music) doesn't make it a short film.  If that were the case, then every camera/makeup/lighting test I've ever done before actually shooting a short film would be considered a short film (just add music).  :P  
  
In the end, this is a great piece, just not a short film.  The execution was good, and the project's use of the RAW recording format was appropriate - the color space really enhanced the color and depth and highlights were saved that would have otherwise been blown out.  Nice work.
