Eh, I'm not seeing it. The designs just don't look tremendously diverse to me. With the exception of the first guy and maaaaaybe the luchador gal, they all have pretty similar body types, similar height, similar weight, etc. Of course, I assume the "diverse" we're using means "visually varied and interesting" and not "non-straight white guy." To that end, kinda falls flat to me - would probably need more exaggeration in the designs to really push all the characters apart from one another. I'd say they didn't do that for fear of making things cartoonish, but going off the bright color palette and how they seem to abusing common character stereotypes (Luchador, tiny hunched over old-man, BDSM whip-slingin' lady.) I find that hard to believe.
Indivisible seems to fit your definition better than this.
