Thank you!
You know how it goes, the best way to git gud is to start practicing. Start small, low scale, restrict your color palette then make tons and tons of sprites. That's what I do.
If you need a quick start with pixel art, check out a guide called "Kiwi 7 step program for pixelart". It's as simple as picking a style, and drawing it yourself.
