Where do i start?

i think you shouldnt focus on anatomy right now

try going back to the basics of basics

draw cubes

they'll help you in proportion and perspective which will be extremely useful once you start on anatomy

i reccommend this video

simplifying the human body down into shapes is a big thing when learning anatomy

drawing cubes will also hopefully give you enough practice to start having more line confidence

this is a helpful video too once youve got boxes down

Ussually you can learn stuff like this, box/cube perspective > cylinder perspective > drawing a bit more of a complex shape in perspective > very simplified anatomy > more complex anatomy

this one too

her videos go more into depth on why you do certain things so if you prefer that then i reccommend her channel

Drawing shapes in perspective is really good for drawing many things but for humans it is really important to learn gesture first before adding simple shapes and after that anatomy
