drawing is all about circles and shapes.yes one can learn just keep everything in proportion.Hitler was exspelled from a jewlish school because his people he drew where taller than the building in the background.thats why he hated jews.they told him his drawing was sh-t work
I'm not sure, only people who are really good at drawing say 'anyone can learn to draw' in my experience
just you need to find out the track and nurture it, that's all
I know how to draw! I taught myself!
