Alone

[RiverNotch]

Alone

Tired Fog, Secluded Mist There's something about "Secluded mist" that makes the mist feels more subtle and less heady in its darkness.
Droning heft of dreary dusk descends, Strong line.
Stars are shrouded, lights are black
    Dark, Heavy, Dull
Closed Doors, Closed Room, Closed House The closed doors already indicate that the room is closed, so try closing off something else.
Dark winter’s weight falls upon an empty home Again, its strong, but the darkness is already known to be descending on the home per the first four lines, so the message of this line is sort of redundant. Try describing something else in this line, like say the emptiness of the home.
Lilting pianos wander the halls Isn't the place supposed to feel deserted? Lilting implies a sense of cheerfulness, so you'll have to reword that.
    Deserted, Hollow, Cold
Crumpled Trash, Clouds of Dust
by the sharp winds, by the cold rains The rains would neither crumple trash nor cause clouds of dust to form. It's not coherent.
Distant grey blocks the sky, cloaks the moon
    Detached, Distant, Alone On "Crumpled Trash..." to "Detached...": This section feels like a repetition of what's already been discussed: this doesn't add anything new to the darkness or to the reader's perception of it. You'll have to change this whole section for the poem to have a stronger ending.

It has a good theme, with plenty of hits when it comes to execution, but it needs quite a bit more development.
