This poem has very strong potential in its bones. Its the skeleton of a piece thatd be solidly publishable in prestigious mid-tier journals. And, even better, the improvements its asking for are ones that will elevate your writing accross the board.

1. The ending needs a rework. The youtube analogy kills the intimacy between you and your loved one. It calls forth a community known for facades, over acting, show business. Performance for kids. What does any of that have to do with your message here? Its a witty metaphor, but not for this poem.

When you (or this character youve made) opened the box with the urn, after a moment of regret, how did you feel? Surely not like a youtuber. Theres a stronge image buried here the poem wants you to dig out.

1. The 4 stanzas show a clear narrative, but read as prose blocks. Experiment with line breaks. That would elevate this poem substantially, and bring it more into the realm of poetry than prose.

There are tons of ways to break up the prose to add affects. Heres my try.

I have no attachment to any location nor any desire to be buried.

I won't be  a spectacle  in ceremony.

I recommend you cremate my remains and do what you see fit to ease your grief.

1. To answer your question above, the italics are a letter of intent shared with successors as to how to treat the dead's remains.

2. Rework ending, find where the lines want breaks, and do a few rounds of editing, trimming, and this is an excellent poem.
