I don't know how to draw people in perspective and I think my spatial thinking is not developed that much, I don't know if it's because I am naturally bad at it or it's just something I have to develop by myself to be good at. What should I do to improve it? What did KJG do to be able to draw his figures in space? "Just drawing" doesn't help, because i've been doing that and I am not better at perspective at all.
