So, I'm still learning anatomy and this tutorial won't be that helpful.
To get familiar with it, I usually use the app easy pose with it and trace the base. Now I'm sure some of y'all are thinking that "But isn't tracing bad?" Well, it depends on the context. You are allowed to trace if the image you're tracing is a reference guide or to practice, but if you trace someone else's art then post it claiming it as your own that's bad.
This next part is about how the body flows with it, I usually added this thing everytime I'm practising without tracing it. You can say it's more of a spine of the drawing. Those small circles serve as the joints of the body. I usually use this if I'm serious about the art but sometimes don't if it's just a fun sketch or something, but it's kinda helpful if you want a reference.
Now the sketch part, as you can see that each part has different shapes. I usually do this so I can get used to the non-traced version. You can also change it into any body type that you referred to or anything, I'm bad at explaining pfft-
And you're done, congrats XD
The design is all yours. Like I said before, you can trace to practice, but don't keep tracing. Let your hand get used to it, it'll be worth it.
