I'm not sure I understand what exactly you mean by pointers to pixel art things? If you want to find other pixel art assets, here on itch there are a lot of resources, but there is also the opengameart website if you want more free assets.
If you mean like tutorials or so, there is a website called pixeljoint and there you can find some tutorial resources. I recommend Derek Yu's tutorial, another one I recommend is Tsugumo's as well as Cure's. Those three are really good for an intro into pixel pushing.
