Thing that worry me here.

First. Glasses. I am serious. Glasses and his gaze kills video.

Second. Items in frame.

Third. Top camera plan with lighting on the floor and more items in frame that must not be in it.

Last. Lighting seems too hard.

i enjoyed the music, so congrats on the audio recording and the multicam syncing,

but i dont think you took the full advantage of shooting in multiple cams, i´m mean the framing was always the same and on two cams it was just too similar, perhaps a better option could of have been to use one cam for the wide angle, static, so you can go back to this one as the safe choice. Another for details, like the bow, the left hand, the head movement, even tele-macro shots, (maybe the gh2 that was on top that way you could of also hide thge non desired elements ), and the other using a framing that is not so similar to the wide shot, changing from first plane to bow.... just, if you have more than one camera use the three to get diferent feelings, different framings

Nice video, nice sound. When recording cello, there are always the twin problems of stair stepping in the strings and shine from the varnish--I thought you handled those very well.

I'll make a few suggestions. I would have patched the few out of tune notes as well as the slide at 1:42, and some of the bass notes are not held long enough, again, very easy to patch. The "sky cam" is fun but it doesn't tell me much about the music of Bach, I would have preferred some detail of both the left hand and the bow, but without the lunar lighting. I like a little blurring on some shots at a moderate tempo to convey the feeling of musical motion.

I can understand why the musician wore the suit, but I always advise the musicians to wear color and texture. A white shirt is always distracting, color and texture draw you in. However, now that you have the suit, setting the grey point lower or adjusting your black point will make the suit look more real in the lighting setup you have. Under lights, formal wear looks too light and need to be color corrected.

And, lastly, Bach is an 85/15 market. That is, 85 percent of audience is an "original instrument" audience: the performance is very good, but very modern; it does not tell the story of Bach. Better to use a baroque cello: when Ma recorded the suites he went to Holland and studied the baroque cello, then made his legendary recording. It adds a dimension and texture to the visual and audio impression. There are a million versions of this piece, you don't want to be in the 85 percent bracket, you want to be in the 15 percent bracket.

Also, I don't get the feeling that it is a live performance, it looks more like a series of clips. If you want it to look live (whether it is or is not), we need to feel more in the space and more in the moment. So for example no one would clap after the first movement of a suite, they would wait until the piece is over, unless it is an encore.
