I know it might not be my place, but I figured it needed to be seen anyways.
There’s a YouTuber who does drawing tutorials about the human body - and some object perspectives - on the website:
It’s not exactly inflation related, but given that plenty of us still need to make the basic of the human body, I figured we all needed a reference teacher for drawing human bodies (unless you prefer object or animals to be inflated, in which case you do you).
Edit: found a resource from this guy’s discord, I recommend going through the lessons, and don’t skip on any of lesson zero.
I’ve seen some of this person’s shorts and many are quite good for learning. I remember that there are some that show how to draw a fat body and many other things.
