After conducting research, I have selected the following articles and books that I recommend for a beginner on pixel art:

"The Pixel Art Formula" by Kevin Hong

"Pixel Logic: A Guide to Pixel Art" by Michael Azzi

"Introduction to Pixel Art" on the website, Envato Tuts+

"A Beginner's Guide to Pixel Art" on the website, MakeUseOf

To make it user-friendly, I suggest organizing the resources based on the type of medium preferred by the requester (book or online article) and arranging them in order of beginner-friendly to advanced. This will allow for a smoother learning experience.
