Perhaps it's also worth mentioning, as some commenters already pointed out, how unfortunate it is that the "greed" demon wound up having a giant, pointy nose. A Tengu feels like the most likely inspiration for this, but it's still a bad look, and the early concept art of a beak-like helmet would have both avoided any uncomfortable implications while just looking a whole lot cooler, to boot.
For everything else about Barbamon's design, it gets a four, because I inherently like all of the demon and devil digimon on some level, but with the better looking helmet face he might have even earned a five.
