A question on punctuation

[Erica]

Are these sentences punctuated correctly?


Knees bent, shoulders back, and a glittering sword held high; the man known as ‘The Ghost Killer’ landed before him.

It swung, and slashed, and jabbed dramatically; illustrating it's master's mortal decree.

Thanks.

You can only use a semicolon after what would function as a complete sentence on its own, so they should be replaced by commas.

I'd write for the first: Glittering sword held high, the man known as ‘The Ghost Killer’ landed before him.

It's simpler and sf someone lands in front of you with his sword held high, you're probably not going to notice the position of his knees and shoulders

For the second: It swung, slashed, and jabbed, illustrating its master's mortal decree.

You don't need the first 'and' and imo the 'dramatically' is not needed. The swung, slashed and jabbed brings all the drama you need to the image. Also, it's=it is not it possessive. You don't use possessive apostrophes with definitive pronouns. The second comma (before the and) is optional as well.
