A few years ago someone posted this on Reddit claiming to have made this character in blender. I thought that was really fucking dumb because it would take less than an hour and it was clearly ai. They argued with me when I said as much, so I did it myself in about 30 minutes to prove a point.
I've heard a few people say that the donut tutorial is not that good for beginners. Maybe it would be useful for you because you already have experience with other 3D creation apps, but for people new to 3D, I've seen recommendations for really basic tutorials for low poly modelling with basic texturing and lighting. The idea is that you acquire the core concepts doing something ultra simple, and then move on to other tutorials that more closely match what specific 3D subject you are trying to learn.
