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.
