Unlike tonyazaka's creepy glassy eyes, yuntayun's yu eyes look like they have some warmth in them. They look like what a "real" yukkuri eye would look like.
I suspect yuntayun might actually be a professional artist outside his yu art shenanigans.
--- This particular comic brings me back to his june bride psycho fare (which I found the story deplorable but the art extemely good for the most part).
