I started learning to draw

Hi, I'm Farbod and this is my first step in drawing
I have been planning to learn drawing for a long time, so I recently registered for a design class and there are two sessions that I attend.
At first, I drew squares and filled them with lines. From the first sessions, I realized that points and lines are the most important issues in design, and you should have a reason for drawing each point and each line.

After the squares, I practiced the types and intensity of the lines, and finally I came to draw the cubes and perspective, and this exercise you see is the last exercise I did.
If you are interested in drawing, just start with small steps
In addition to the general entertainment, you will relax. Thank you for supporting me
