I initially disliked Whis's design but was seeing some more recent eps where it didn't bother me....then I noticed why
his makeup is slowly dissapearing
contrast how he looks early in the series
to how he looks now
it seems like as be becomes more heroic they're making his design less effeminate
edit: someone else also pointed out that the Artstyle was changed rather radically for the current arc, the designs are closer to the designs from Z, and as you can see, in the current arc's eps, the colors are extremely muted for some reason
