I need some examples of what is considered good pixel texturing and what is considered bad.

Trying to learn what to look out for.

look up texel density. it's not a huge issue but it can look very bad when done poorly; pic related is a particularly bad example. notice how the size of the pixels varies drastically all over
it can be managed by using UV checkers, plus an add-on I can't remember the name of
it's not unheard of to give more detail to more important or smaller props / parts of a character though, so don't worry about it too much, a lot of PS1 games did it too
speaking of, I'd recommend checking out models from actual retro games to see it at its best

Thanks for the tips! Is this add-on (https://github.com/noio/Pixel-Unwrapper) perhaps the one you were talking about?

I was referring to Texel Density Checker. I never managed to get to grips with it, but it should get the job done
