Luke aka Sadface is a pixel artist who also creates these fun and informative videos that show you how to make pixel art animations.
They’re all available for free on YouTube, and there’s a cool thread of excerpts on IMGUR.
You can support Sadface_RL on Patreon, and check out how every time there’s a new video, there’s a corresponding image (GIF) based demonstration over at the Patreon.
Below: “Making an Archway,” and “Pixel Art Tutorial / Walkthrough on Trees without Leaves.”
And a fun bonus, below: “Self-Assembling Pixel Art.”
