I've noticed that 2D artists/non-sculptors who engage in strange mediums or techniques generally only make realistic closeup portraits of people. I saw the headline, thought "neat, but I bet he just makes normal expressionless faces." Opened the page and it seems like that's the vast majority of his work. As an artist myself, I'm always like ehhhhh when I see this. Feels a bit like the kind of stuff you see for sale in tourist areas.
The technique is cool though.
