Working on my metre

[Achebe]

Hmmm...I couldn't detect any cadences in what you wrote, for instance:

I am sitting at a cafe sipping on my latte sweet.
Misa pumping breastmilk from the sleeping wombat's swollen teat

has rising and falling accents, whether i write it out like the above, or as

I am sitting at a cafe sipping on my latte sweet. Misa pumping breastmilk from the sleeping wombat's swollen teat

but I don't get that in your piece?
