Well i'm going to give you a little help on this poem i hope you dont mind. I think you should capitalize each letter of each line to make the format look much neater.

These two lines were much longer then the rest and need to be trimmed down a bit maybe like this for example:

In this sad and mournful house,
I think about your body in that grave,
And this is when i seem to crave.

I think it would make the poem look a little neater. maybe if you put this poem into stanzas. Add a little to it, it would become a 5/5 from people who have read it instead of a 4.

Good work tho. well done~mel
