I wrote a thing

I had to write a narrative poem for my creative writing class. I just finished it and feel like sharing it. Feel free to tell me what you like/dislike about it :D

Green

Green.
Snake’s venom, pumping through ruby blood, coursing, coursing,
Injecting muscles with energy, making bonelike fingers clench, clench,
Gripping the armrests, veins throbbing behind the eyes, staring, staring,
Fixed upon the door as headlights slow and rest outside.

Door slams, engine rumbles, retreats into the night, footsteps, footsteps,
Key scratching at lock, twisting, door swings open, revealed, revealed,
The tramp, the snake, hand slapping light switch, thrown into view, swaying, swaying,
Returning stare with a startled face.

Red.
Twinkling like lights on a Christmas tree, shock, ignited, burning, burning,
Engulfed in crimson flames, devouring thoughts, spreading, spreading,
Tousled clothes, smeared lipstick, untied shoes, spotlight, spotlight,
Feeding the beast, fueling the inferno in the armchair.

Rising, shouting, gesturing violently, biting words, accusing, accusing,
Whore, traitor, drunk, liar, scathing tongue, lashing out, roaring, roaring,
Hand shoots up, smack, red stain on powdered cheek, stinging, stinging,
Stunned silence gives way to indignant screaming.

Silver.
A glint of light, there, on the counter, beckoning, beckoning,
Takes it in hand, cold steel, vengeance's sweet vessel, turning, turning,
Tight grip, wild heartbeat, tangled thoughts whirling, whirling,
Raises blade with a madman's arm.

Angry screams, frightened shrieks, crying for mercy, stumbling, stumbling,
Trips, falls, sprawls on the ground, sobbing, pleading, pleading,
Soundless next to fury, blade comes down, ripping flesh, again, again,
A red coat for grinning silver.

Blue.
Brown handle protruding from ruined chest, blood trickling out, slowing, slowing,
Fearful eyes fading, warm color draining away, condemning face frozen, frozen,
Forever trapped in the insane moment, pulling him in, sinking, sinking,
Slumping against the wall, red staining his skin.

Monster within, screeching laughter, satisfied, satisfied,
Drowning under guilt, overflowing, tears cut through sweat, horrified, horrified,
Hammering heart mocking, impossibly alive next to empty husk, unfair, unfair,
How a beast can go on after taking all.

Black.
Heart settles into slow rhythm, tears dry on cheeks, clenched fists uncurl, calm, calm,
Stands, grabs limp arm in firm hand, drags through the still house, calm, calm,
Out the glass door, down the steps, to an empty graveyard, calm, calm,
Nothing but calm as he takes up his shovel.

Back inside, quiet breathing, to the hallway, breathe, sit, calm, calm,
Blood soaks through clothes, no thoughts, no sound, calm, calm,
Lifts blade, watches red drip from silver, inviting, calm, calm,
Plunges into heart.

Calm.
