grammar - Participial Phrases

Is the sentence below grammatically correct?

I repeatedly punched his face until I passed out, my arms sliced a few times by his blade."

I know what participial phrases are; I read about them here. I know how they describe a noun.

For instance:

Watching the TV, I heard a sudden yelling from my mom forcing me to turn off the TV.

Here, the sentence has two participle phrases (both are verb-ing modifiers) modifying different nouns: the first one is "watching the TV," which tells us what the subject is doing; and "forcing me to turn off the TV," which describes what the mom was doing. And I also know that "yelling" is just a gerund and not a participle phrase.

I also know when to use a comma on sentences with the participle phrase showing at the end of a sentence.

My mom screamed when she saw her, terrified.

Here, the mom is the one being modified by the verb-ed modifier, or generally the participial phrase, not the person the mom was scared at. But if a comma wouldn't be there, the sentence would be interpreted as the subject's mother screaming when she saw her being terrified as well, which is a bit weird and absurd.

And I know the concept of dangling participial phrases too.

Clenching my fists, my brother got scared of me.

The sentence would mean that the brother is the one that clenches his fists, which is clearly not the idea the writer wanted to show.

So to avoid this, the writer must put the noun as close to the participle phrase as possible.

Clenching my fists, I saw my brother getting scared of me.

Here, the phrase is much more closer to the subject and the sentences is much more understandable and logical.

Now, for my question, I haven't found any examples like the one above on the internet at all.

I'm really struggling with these kinds of sentences right now. It doesn't have dangling participial phrases, and it is also punctuated correctly for the readers to understand, but I can't seem to find any sentence on the internet similar to this.

To make my question clearer, here's another sentence:

I walked toward the coffin, the skies portraying my emotions—gloomy, depressed and sullen.

Here, "the skies" is clearly being described by the participial phrase, "the skies portraying my emotions—gloomy, depressed and sullen." And there are dangling participial phrases here. So . . . are these sentences correct?

Are these sentences—with a structure like this one: comma + noun + participial phrase—correct?
