Garbodor is a bad design, people mock how unappealing it is. It would not be a terrible design if it looked "attractive" unless you think it being attractive means to be "beatiful" or "cool" looking. You could have made it look scary, intimidating or dumb-cute in a charismatic manner. Many liked and used alolan muk, when its basic concept is somewhat similar to garbodor.
Designs looking good is something more subjective, something as logical as simply communicating interesting ideas, is not what makes people like the design. You could also say pokemon like swalot and electrode have simplicity in communicating their concepts, just like crobat, but unlike crobat, not many players choose them for their teams, nor think they have appealing designs.
What makes a good pokemon design, is its appeal. It doesn't have to be liked by everyone, but it needs to be liked, because unless it is a gimmick like unown, voltorb, etc, the purpose of creating a pokemon is for someone to say, "this is the one i like, you are going to be my partner".
A pokemon fails as a design when no one, or practically no one thinks that. Therefore you should consider that what will make a deisgn look better, will make it be liked by more people.
Some may like scyther while many do not care about it, some may like quagsire while many do not care about it, some may like lucario while many do not care about it, and some may like primarina while many do not care about it. There are many ways of making a design that attracts different types of pokemon fans, but if you opt to design something that looks like jynx, diggersby or squawkabilly, you are producing bad designs, that will be attractive to a negligible ammount of people.
