Well I have read through several of your poems and think that this is one the better ones. But I tend to like dark poetry anyways. Anything that doesn't sound to cliche but makes you think and offers some kind of message in the poetry is always something I search for. You have managed to pull off a grim story with a fantastic ending. The thought of being buried alive is horrific.

>>Twice the sun has rise and set
And not a reason to regret
Darkness then fills opened eyes
Shriek with terror and surprise<<

I did feel that in this stanza you should change the rise to arose or risen. I am not great in English as in past tense and what not but believe that either would work in this case. To use the word rise is a future tense as the rest of the poem is past.

Thank you very much! I'll definitely make that change, I was trying to make the flow work while still keeping the line and somehow overlooked the word arose :)
