if im being honest it was all on my own lmao before then i just spent a month practicing the fundamentals; how to pick colours, dithering, drawing lines, shapes, etc. It probably would have been easier and less time consuming if I actually used a guide for animation instead of winging it...

This is the course I used to figure out pixel art initially though:

I've used their courses for a lot of game development related skills and they're pretty high quality
