There are just so, so many problems with what this guy's doing. He clearly has a very weak grasp on the concept of anatomical structure.
The guy said he drew cartoons all the time in college. I have a feeling that it either wasn't an art college, or he dropped out of art college, or he just got really, really lazy.
The other alternative? He is Troll Force Personified.
What's crazy to me is that there's a few people defending the guy, using arguments along the lines of 'You don't have talent and you're jealous, you're just hatin' on the guy', or 'The man is drawing cartoons of course it doesn't look like Da Vinci masterpiece!! Cartoons aren't supposed to follow reality!!!'
The first argument made me laugh so much, when after checking out a few of the folks who were very critical of the tutorials turned to be much better artists. The second one makes little sense too, because even cartoonists are supposed to understand proportions and how to draw real people (because once you know that, you can exaggerate a lot easier without going into the uncanny valley).
Don't even think about saying the guy's drawings look like that because they were done under 5 minutes, considering even in under one minute a lot of decent artists can make a good sketch.
Seriously, either the dude making those so-called 'tutorials' is a troll or he lives in a sad delusion that he's a skilled artist.
Remember, the cruelest thing you can do to an artist is to tell them their work is perfect when it isn't flawless, because then they'll lose the motivation to improve.
Do yourself a favor. Look for tutorials on drawing manga elsewhere on youtube, like Mark Crilley (username markcrilley) or for something non-manga like this good Painting Fundamentals video by Marco Bucci--> [link]
