First ditch that shitty tutorial pic and wipe it off your system.
Gotta second this anon >>3817613
, perspective is what separates amateurs and real artists.
You should read the sticky post on this board as well, it links back to a helpful beginners guide for the basics.
A very useful channel for art on YouToube is also Proko. He teaches many important art fundamentals and anatomy in video format, so make sure to watch these.
You should not forget to practice basic shapes. Cubes, Spheres, Cylinders and other basic 3D Shapes, everything in the World can be broken down into different variations and combinations of these shapes. For beginners it is important to simply complex structures into simple ones, simplifying the ribcage into a Cube, simplifying the arms into cylinders etc.
When drawing something you must first break the thing you want to draw down into basic 3D shapes and then build on top of that foundation. This is an important thing to remember. Don’t fall into drawing lines and contours exclusively. Think 3D, and imagne eveything you draw as 3D.
That’s all I can come up with right now, so good lick from here on, anon.
Becoming good at art is a long, tedious, time consuming process but if you want it you can do it.
Right now, as a beginner, focus on 3D Shapes, Structure, Gesture and Perspective.
Don’t get too much into complex anatomy yet. It might distract you. You only need to know about the basic proportions of the average human body.
