...Been playing around with attempting to get dithering, playing around because shaders/post-process effects is not my strong suit, learning slowly but surely though. I'm not even sure if this is what you'd call dithering but it's a start I guess with low res.

That's not what we call dithering. xD Yeah, right, you have to start
somewhere! If you are serious about dithering you better start out with b/w
dithering first, i.e. in producing halftones between two full tones (black and
white), which is very important conceptually, and gradually include more and
more full tones as needed (i.e. black, ..., gray, ..., white) and dither
between those such that you can produce arbitrary shades with respect to a
given tone table and dithering technique. While you're doing so you will learn
to apply many of the different dithering techniques, patterns etc. and will also
learn many of the fallacies but also advanced ways to make dithering really
look good. This knowledge is required to produce fine color art dithering
where you will apply gained knowledge to dither between color tones producing
this very distinctive look given your graphics a special appeal. There you go!
If you post pictures showing dithering, you may also post the original one.
