No worries for answering late, thanks for responding! I've been doing pixel art for about 1.5 years. I got started by watching youtube tutorials and other tutorials online. HeartBeast's "let's pixel" series helped me a lot. I used that to just practice drawing random things. I also looked at this guy's patreon page a ton. He posts these fantastic 'one pager' tutorials on specific little things (for example, how to animate a 'top down attack').
The last thing I did was I would try to imitate art from games that I liked. I would frequently record myself playing games with good pixel art (i.e Hyper Light Drifter), and slow down the recordings frame-by-frame to try and see how they animated certain things (I think I would just use my iphone camera and record in slow-mo haha).
I hope that helped!
