I decided to forgot what I learned from the pass three years and read more from Scott Roberson's book how to draw, drawing and sketching objects and environments from your imagination. I'm trying to relearn perspective and look at is in his eyes through the book.
Perspective is pretty hard to understand from his point of view, using a lot of math. Which I'm not that good at math. But it's a start, when I'm done with the book I hope to understand what he is saying and learn how to draw environments from my imagination as well as from life.
I also put a hold on learning how to draw people to focus on landscapes and objects. I'll try to learn how to draw people next year.
