Have you ever tried writing acrostic poem based on the letter of a person's name? I did. Why don't you try writing acrostic poem that contains more words per line? It is equally interesting.. Good work!
Mnemonics is cool, too. You'd be surprised that a poem can be not just a work of art composed of words. It can even be a painting. the mnemonic aspect is the designs and colors to which you have assigned a "meaning" which can be as complicated or simple as you want it to be. My own innovation.
