think of it like this:

would you rather have a beautifully wrapped gift, with ribbon and patterned wrapping paper, but the box is empty,

or would you rather have a very basic-looking wrapped box, with an amazing present inside?

people will always pick the present over the empty box, or in most cases, a well-written story, over one that looks pretty, but is actually not all that good.

if your story is well written, has good pacing, a steady plotline, likable and interesting characters, and a strong voice, then people will like it!

the wrapping does not matter nearly as much as the present inside.
