I'm on tiktok all the time and I get those types of videos A LOT. The "You're drawing your side profile wrong", "You're doing x,y,b, wrong" and it just irritates me to no end! I see it here and on youtube too. Its fine to offer art advice or even a "Want to know how I do this thing? Here ya go!" but to start a post blatantly saying "Hey just a heads up you're doing your art wrong! Here's how to fix it!" is the most exhausting thing to read.
I was watching a tiktok about a guy saying "If you draw your side profiles like this, you're doing it wrong! Here's how to do it CORRECTLY" and it was NO WAY NEAR how I draw side profiles, obviously, because there is no One Right Way to do something with your art. In my opinion, the way he went about drawing a side profile was overly complicated and confusing, and if I was a beginning artist, and if I'd had seen that, it would have deterred me from learning how to draw side profiles because "Oh man if that's the right way to do it then I don't know... that looks really hard...."
Draw in a way that works for you and makes sense for you. Seek out tips and tutorials and help for sure, but don't take one artist's word as gospel. We all learn differently, and what works for that guy definitely doesn't work for me, and its definitely not the one correct way to draw. And making fun of beginner artists is never chill
Anyway here's a bunch of side profile examples and the last one is literally how I sketch it out before going straight into everything else. Its simple but it works for me and I what I need for my art, but I know it wouldn't work for anyone else (and its why no one will ever catch me telling anyone else to draw how I draw).
