>>4767236Anon explained it a little weirdly but he's still right. People obviously know what things like perspective, proportion are but they're not sitting there mindlessly grinding them day in and day out. They learn to apply these things while they're creating. So say you want to draw a cute girl with a sword. Well maybe today you want to try making that drawing a little more interesting so you try some of these nifty perspective tips you found online. People aren't just like okay let me go master all of the fundamentals before I even think about drawing for fun. You don't even do that in art school. Hell, you'd probably never even make it to the art school part with that logic since you kind of need finished pieces in your portfolio.
