Hello again! Here's another channel to check out. If you're interested in low-poly modeling, Imphenzia has quite a lot to say about it. He has many videos revolving around 10-minute modeling challenges. But he also has a much longer video, Learn Low Poly Modeling in Blender 2.83. It's loaded with tips and tricks as well as how-to. I recommend checking it out!

Some of these videos are very long! I like to watch them fast as possible and sometimes rewatch the highlights. I suggest increasing the playback speed and turning on subtitles. If you have 2 monitors, you can open Blender in one and play the video in the other. Then you can work along with the video, pressing the pause button as needed to do more in Blender before moving on.
