To be honest, I feel pretty self-conscious in crowds like this Ren Fest where other people may not. All part of my introverted demeanor. All that to say, many of my captures were quickly done and on the fly as opposed to giving much thought and effort to the cha cha.
In this case, if you notice at the bottom of my post, I indicated the focal length was 110 mm. This was a zoom lens which tends to counteract the normal or standard stereo base. Not knowing I was going to extract the background until processing, I might have thought about giving it more base but the removal of the background adds to the flatness you're perceiving.
I'll attach a 2D image of the capture since you were interested in the original background.
As you can see, it had an out of focus background (It was a zoom lens), and was under a wooden pavilion which added to a
vast different in contrast. Thankfully I was able to compensate to some degree because I shot in RAW. The shot was also taken at an angle which may be perceived as off kilter, and there was a white streak running vertically. (That's why I said in the original post that the background had problems).
When I extracted the background I spent hours trying to replace it with a cha cha foliage background I shot at Clear Waters Park that same day. I finally gave up on it because of frustration and the fact that I could hardly see at 4 am. (This 3D foliage shot is also attached).

Hey Brian -- Since you were doing Cha Cha (a skill I still can't seem to master) I would have gone a bit more hyper to accentuate the depth changes a bit more. Nice subject. What was the original background?

At the Renaissance Festival I spotted this wooden statue of a Knight.
I thought it best to extract the background which had problems.
