Too Many Samples = Unrealistic? I've tried experimenting with the amount of samples, the size of the tiles, etc.

Do you think TOO much samples may make it too, like, just too clean?

What do you think would be a good preset so you JUST remove the noise, and it (the image) isn't TOTALLY clean.

I have to post links due to file size:

You see how it's like almost too many samples? I only messed with the blurs and glow effects on PDN, but you know what I mean?

Maybe its just because I'm visually justified to darker scenes?
No. Larger sample numbers make the image more accurate. If images appear to lack variation and imperfections, (I assume that's what you mean by clean) you can manually add them. This may include 


Particle systems in the air for dust
Manually added light 'shafts'
scratches on surfaces
fading, or slightly different shades of colors
high amounts of randomness (not weirdness, RANDOMNESS)


All of these can go to make sure your picture look less 'perfect' although most of the time, you don't need to add them.
It all depends on how closely the final will be observed, and how critical your audience is. (or how dirty, being the opposite of clean, you feel comfortable with.
