Without a definition of what the author means by “polished”, this reads like a student who got a C on an assignment and isn’t happy about it.

To be a better submission, the author needs concrete examples that set the context for the reader and helps clue us in on what “good” and “polished” means.

Side note: In my experience, very often one person’s “polished” is another one’s “good”. This is often a key to detecting the quality of the author. For example, if you think of films or books, exceptional creators have made amazing works out of the most mundane topics (eg Office Space). Another way to put it: “Anything worth doing is worth doing well”.
