Obvious Points:
- Keep the style consistent. I'd advise against using this style in this scene if it's not generally used in other scenes.
Somewhat Obvious:
- You have a habit of using several short sentences. This style works fine, but you need to break it from being bland. There are also times where you force it, and the transition of sentences is awkward. (e.g. Broken glass covers the floor. Piercing into my skin.) You could back this up with good direction, like 'Broken glass covers the floor.' *cue blood drips* 'Piercing into my skin.' Otherwise, you need to connect them better. The formula, [Noun]. [sentence in relation to noun], works well. (e.g. The broken window. A lifeless corpse sits near it.)
Some personal remarks here:
I feel like I'm manipulating your style with the suggestions here, so feel free to disregard. I'll add more remarks later.
A suggestion my workshop teacher once gave me was, "Write down the same scene in the most blunt, and least literary way you can. Compare the two." I'd advice you try the same. You could also do so with your normal style.
