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.
For me, 30 weeks, probably (I have no Blender experience).
I had a couple of years under my belt before I made this.
