I seem to have spotted an UFO, round in shape and gray. bu doğru görünüyor mu?

@fishyrobb

Are you good at English grammar as well?

@fishyrobb

Ah.. What a luck!

I'm curious to know whether it's okay, like in my sentence, to describe a noun with adjectives with a comma.

I'm not sure whether it's informally and frequently used even in novels to write that way.

I seem to have spotted an UFO, round in shape and gray.

With a comma, "Round in shape and gray" is describing the UFO, but I'm not sure whether this is frequently used.

The similar examples..
‎I seem to have come across the criminal on the road, muddy and bumpy
I seem to have come across the criminal on the road, tall and bald.

I don't even know whether the above two sentences are acceptable

@fishyrobb

To specifically speaking,

‎Can adjectives describe its preceding noun with a comma?

What I'm asking is not about the typical version of 1.

I have often come across case 1 in novels, but I'm not sure whether I have seen cases 2, 3, 4 used in novels, though I seem to have happened by at least one of them. Would you tell me whether cases 2, 3, 4 can be used informally according to context or you have seen such cases in novels? I think they're all possible informally, though not grammatical, if context is clear enough that the adjectives are not seen as describing the subject, and I want some examples for each case as well.
(DON'T FORGET THESE CASES ARE INCLUDING A COMMA OR COMMAS)

1.Subject, adjective and adjective, Verb Object
(Adjectives describe Subject)

2.Subject Verb Object, adjective and adjective.
(Adjectives describe Object)

3.Subject Verb Object 1 preposition Object 2, adjective and adjective.
(Adjectives describe Object 1)

4.Subject Verb Object 1 preposition Object 2, adjective and adjective.
(Adjectives describe Object 2)

Thank you very much!
But I can't understand "You can follow a noun". What did you write it to mean?

@fishyrobb

Thank you very very much for your lesson!
I get it all!
