Animating pixel art, where to start?

Hi everyone,

I'll start saying that I'm new to photoshop and have no drawing skills.

I have always been interested in pixel art animations, and I'm trying to get familiar with some graphic concepts to start making some, just for fun.

I searched for something online but tutorials and threads mainly refer to very simple 8bit style pixel art, like old pokemon/super mario sprites, which I love, but what I'm really interested to is this kind of animations:

(No spam inteded, just for example)

I know it's impossible to get that kind of result immediatly without any basis and knowledge, but I thought maybe someone expert could help me by telling me where to start and what to look up for.

Thank you!
