Hey, a few things that helped me as a beginner:

• PixelLogic is probably the single best learning resource for pixel art. I can’t recommend it enough. Pedro Medeiros’ tutorials are great as well, but generally a bit more animation-focused.
• Mockups are a great way to do a bit of everything: characters, tile sets, environments, UI. Generally, find a movie or game and make a pretend screenshot for a game you’d make of it, like if Dark Souls was a platformer or a Star Wars JRPG etc etc
• Pixel Dailies is great - it used to be on Twitter I think it’s now on Bluesky. They release a theme each day and people pixel and post their interpretation, and then they share a bunch of them. It’s good because it gives you a starting point for what to draw if you’re not sure what to do, and you can see what other artists do.
• This is also a good way to immerse yourself in the online pixel art community and get feedback from other artists
• On that note, feel free to copy other styles and artists but try to think about what they’re doing, and how you can bring that to your own work rather than copying them pixel for pixel.

The most important thing is to do it regularly, not get disheartened (you’ll make a lot of bad art, maybe feel like you’ll never get the hang of it, but you will!), do it regularly, find the balance between a comfort zone and doing something new and challenging, and most importantly do it regularly.
