Sentence Diagramming Challenge ~ Take Two, The Results Show

Did any of you give the sentence diagramming challenge a try? I tried to make them easier, but I had a tough time with ‘came thundering’ on sentence #2. Is that a verb phrase? Is ‘thundering’ a modifier? I bet I diagrammed it incorrectly. And I found mistakes on sentence #3 after I diagrammed it, so this is my second try.

Sentence #1: “The view from that point was a magnificent one.”

Sentence #2: “St. George lowered his spear, bent his head, dug his heels into his horse’s sides, and came thundering over the turf.”

Sentence #3: I’m going into Society, I am, through the kindly aid of our friend here, who’s taking such a lot of trouble on my account; and you’ll find I’ve got all the qualities to endear me to people who entertain!”

ETA: I’ve tried to get an expert opinion on sentence #2, but the jury is still out. I don’t think ‘thundering over the turf’ can be an adverbial participial phrase, so the other two options are ‘came thundering’ as a verb phrase (can ‘came’ be a helping verb?) or ‘thundering over the turf’ as an adjectival participial phrase modifying ‘St. George,’ but that just seems wrong with the compound predicate. Care to vote one way or another?

Here is Hannah’s diagram for #3. I think we were in agreement:

Are there any expert diagrammers out there who would like to shed some light on the subject? Did we do something incorrectly?
