Bleh. I agree. Too depressing... Why do you inhale when it smells like death? I don't get it. >.<

You have issues with erroneous comma splices as well as tense. Yes, definitely tense.

Perhaps you could describe the machines instead of simply mentioning them? I think it's a point to be emphasized.

Maybe you could also mention some colors? Cuz the work seems... I dunno, black and white to me, somehow...
