Going Dirty

I’ve been trying to find some tutorials on a particular style of Graphic design.

I’ve always used clean lines and white space in the past, but I’d really like to branch out into a more dirty or degraded style.

I’ve been googling around to find some tips or tutorials, but I don’t really know what search terms to use.

Here some exmaples of the styles I’m trying to perfect.
