Advice on getting started with 2d vfx.(Interested in combining it with 3d animation)

I am trying to learn 2d vfx in order to add it to 3d rendered animation i.e beaststars, i cant draw, but i feel like the drawing required for 2d vfx isn’t complex, i have not found tutorials that really help and i don’t even know what software to use, i currently use blender for animation.

any advice on courses, software is highly appreciated

ps: i know that i have been asking all sorts of questions here from game vfx etc, and i might look like i lack direction, but i am honestly just trying to figure out a lot of things, and i apologize to anyone that might piss off.
