Well, if you really want a rating on just that excerpt...I would say 2/5 stars...? It functions, but it doesn't do much else.
The wording is kind of awkward, and I would say the biggest issue is that there's not enough imagery.
"The ensuing carnage" --> what actually happened? What kind of carnage ensued? Tell us!
"Continued her offensive attack" --> A, I wasn't aware that she had started an attack, let alone 'continued'; and B, what attack? Tell us what she did!
^Hopefully you see what I mean. Seems like you're going out of your way to be vague unless you absolutely have to describe something, which doesn't exactly make for a compelling fight scene... Choreography is more important than many prose writers give it credit for; if you want the audience to be immersed in the action, you need to actually...tell them about it.
