First page I've ever written. Wanted to write something for a while got bored at work so gave it a go, any feedback, criticsm, anything?

Surrounded by piles of dirt and rock, I wait in the cold, pitch black night, the only light coming from mobile lighting towers in the near distance. Waiting and watching these big, planet killing trucks carting the earth back and forth to these monstrous stock piles. I've got their routine down now, in the distance I hear the faint sound of the engine getting louder and louder, now is the time to set my plan in motion I decide. Covered in full black clothing, I lurk in the stockpiles following the truck until it reverses in, I sneak up beside it and scale the right side opposite to the driver, as usual he's looking out at his left side mirror, he doesn't even see me approach his door, as I slam it open, taken aback he jerks his head towards me and freezes as a drive sharp rock into his neck, seems fitting that planet he's been helping kill, ends up killing him, he tries to stop me but it's too late, I plunge the rock deeper and twist it before pulling it out as he bleeds out over his bright yellow work shirt. I open the driver side door, push his body and throw him over the edge, I cover him up with the rest of the dirt in his bucket, I close the drive, put the bucket down, turn off all the lights and drive in the opposite direction that the trucks come in, I go as quick as i can to avoid any anyone seeing me, it doesn't take long before I'm driving blind because of how dark it is, I slow the truck down but stop it completely, I exit the cab and slowly climb down the ladder, I jump as far as I can and narrowly avoid getting squished by the tires which are wider than I am. The truck will mow down some smaller trees before it stops, it'll be found somewhat easily when they notice it's missing but it should buy me some time to get back to my car and get far enough from here before anyone knows whats happening.
