Brandon James Greer[0] has some really good vids on pixel art, including 1-bit. I recommend trying it out for yourself in Aseprite, or if you have an iPad/Apple Pencil, Pixaki is actually really nice.

You can support the artists by buying their existing artwork or commissioning new work.

But you probably meant, "how do I make art?" Art isn't really even a defined thing. Go throw some paint at a wall and read the Art Of Asking Silly Questions by Sunkist ;-)
