That’s only intellible if I think you’re a native speaker of a pro-drop language where the copulative is dropped. Because of the structure of the English, it is ambiguous what “missing” here is appositional to, since participial forms in pro-drop languages are usually conjugated according to their case, number, and gender (at least among the Indo-European languages), so I can’t tell if the fragment is missing a sentence or if the verb is missing a fragment (or other, numerous possible interpretations).

Its not a bad thing to be wrong, since, when it comes to expression, one can never be right. But it is still better to know the best way to be wrong, a wrong way that cannot be made right. And then you yourself will have created something entirely new.
