Shaco Action Scene

Hi guys, I wrote an action scene for the first time. It's for a fanfic, could you guys do me a favor and check it out and find anything I should focus on improving on? Thanks so much everyone.

Shiv immediately got to work, leaping onto the nearest guard, who was busy winding up a finishing blow on a downed comrade. After dispatching the man coldly and efficiently, running him through with both knives, he quickly jumped away from him to find that he was now surrounded, six guards closing in on him, sneers on their faces. Shit. Shiv closed his eyes, focusing as he felt the vibrations in the ground, caused by their footsteps. Six people. Two, two, and two. Alright, here we go. He instantly sidestepped an ax aimed vertically at his head as he reopened his eyes. One. He followed up with a deep stab in the back of his assailant, who had all but lost his balance from missing the blow, and with his free hand sliced into the chest of guard number two, at his right. Two. Firmly planting both feet on their bodies, he jumped upwards into a backwards flip, the other four guards exactly where he predicted, in formation and charging straight at him, or more accurately, where he had been a moment ago. The downside of formations, it makes you predictable. At the peak of his flip, as he was upside down, he stabbed into the backs of the two middle pilties, and used the leverage to swing himself back down, legs straight out, kicking into their knees from behind._ Three and four._ The momentum from the kick launched the two men in front of him, dislodging his knives from their backs and throwing them into the first two. Goal! Shiv found himself in perfect position, right in between the last pair of dumbstruck guards, and all it took was a raise of the arms to either side of him to finish them off as well. -End

Thanks again, Supthisgamesucks
