The author's art is pretty good, so it's a shame he always pigeon-holes himself into "first person" POV and very limited paneling. IMHO it really limits his growth as an artist. He's been doing that same POV over 1000 updates now on Pixiv over the last ~5 years or so.

It hardly counts as POV when the character hardly looks down and is just a passive observer like a static camera on a tripod. I still think there needs to be more POV, and that it'll eventually happen, but not like this because what is the point of adding a couple of fingers or strands of hair if you're not going to mix it up and get freaky with the perspective?

Greg Soujou isn't an impressive artist, but he has been relatively more creative about exploring POV in different situations and has given a glimpse of what it could be like if taken to its natural conclusion. I think an artist could definitely make full POV comics work well if they used interesting skin gradiants and changed the poses and objects frequently enough to prevent it from becoming boring. After all, people don't normally complain that strip teases or having sex are boring just because they're physically constrained to "one perspective" and can't float around the room like a mangaka does.
