"Perspective" is difficult and tends to be shunned, but "one-point perspective" is not so difficult.
In this video, I think you can understand the mechanism of "one-point perspective" through a simple way of drawing a window.
If you can understand perspective even a little, the world of "illustration" will expand 😊
Please take a look.
Please set "automatic subtitles" to your native language when viewing.
I run an "illustration channel" on YouTube.
I think of easy-to-understand drawing videos and post videos frequently.
I also posted an "illustration making video".
