well, it takes place 2,000 years in the future, my "science" behind it is that holo-technology has been perfected now. It interacts like it's real (ie, you can grab a holo panel and move it around, tilt it, walk it from one side of CNC to the other)
That's not what I meant.
Your science works fine for imaginary stories and people.
I'm talking about the aspect of filmmaking that I'm sure you already are aware of; artificial images generally need to be altered for the imagery to appear believable. This is why imperfections are generally added to props and images in big budget movies... to make the images/effects blend in with what is real.
It's that Star Wars 'life-in-a-lived-in-real-world' look versus classical Star Trek 'it's-obviously-a-prop' thing. It's about images with a visible history. In short, imperfection can help with a viewer's suspension of belief as we have an expectation of what is acceptably real. If everything looks perfect then the world doesn't look lived in (i.e. it has no apparent grounding in reality or sense of history) and suspension of belief is harder to achieve.
More info than I meant to relate or that you likely wanted...
If your aim is more stylistic than hyper-realistic then there may be no need.
Added: One of the most effective alterations of CG images can be gained through the use of the Post Effect known as 'Film Grain'.
It's quite handy in adding the imperfections that help us recognize the images playing on our screen as a 'real'.
