Too clean CG?

I am working on a project of combining 2D illustrations with some 3D CGI environments. One of the critiques I have gotten from one of my friends, is that they felt the CGI was "too clean". I have read online about some techniques to kinda combat this, mostly from the production of Archer, which they merge the textures with brush stroke images to give it a more painterly feel to it. My friend also showed me about using a camera to project a texture over the scene as well. Just thought I would post a discussion online to see what other techniques people have opinions on and get your thoughts before i start experimenting a bit more with the techniques before I pick one.

I'm using C4D R13 on the project and compositing in AE, just for the record. Thanks in advance for any feedback. I appreciate it!

Software actually matters little in this regard, but rather the stylization employed.

Any which way, usually adding (in no particular order) volumetric effects, atmospheric effects, depth of field (and bokeh), lens flares (though they're fickle) or just plain old noise (again, depending on the visual style) remedies this. That's pretty much I can give to you, blindly.

A rule of thumb when it comes to 'dirty' CG is to strive to add all the little imperfections that photographers strive to avoid.

I cant know how much you have done this before but one huge mistake that people make is not chamfering or beveling edges. If you dont split the edges of your objects the result just hurts the eye. You see this with cut rate archiviz and the cumulative effect can make you ill.

Thanks for the feedback so far. I generally do more motion graphics work, and this is a personal project where I am working on actual environmental settings. So one of the shots is in a city street and I am using the GSG city kit. I know I have more to learn about exterior lighting because I have a feeling that might help but I also wanted to hear what everyone else has to say as well. Thanks again for the suggestions!

This. And bump or displacement on said bevelled edges to break up your specular (where appropriate).

I didnt know you were using a city generator.

You should post in the wip section and provide some images so you can receive better help. Also if you can get some reference images as an example of what you are shooting for that would assist the process as well.

I'll get some stuff posted up on vimeo and get it in the WIP forum and provide a link so everyone can see what I am referring to. Thanks again everyone!
