these sausage men are great, and I personally consider their cartoonish, everyman nature to be a selling point. Bob's Burgers has a similar aesthetic, and people complain about it. Anyone who says that its a bad decision though is empirically in the wrong.

No one gives positive feedback on anything, so you are almost always doing the right thing by ignoring negative feedback below some threshold. I hope that this person and their friends have not one iota of influence on your character design.
