(1) It should have been "He painted love quotes WITH pastel colors ON a scented stationery." Stationery paper is redundant.

(2) Down pouring rain is redundant.

(3) In "making you thoroughly chilly wet of his lines," you could have said: because of his lines.

(4) There would be no other better word to substitute EYES; not even Iris. "Eyes" is profound and symbolic.

(5) Rainbow-colored envelope is hypenated (?)

(6) Serious chin does not sound serious to me. It's a little funny.

(7) I like the phrase ELUSIVE LOVE POTION since it makes the poem magical.

I really enjoyed this. I found your style and wordplay modern, provocative, and original. Although I had to read through twice as the poem is confusing in a place or two.

Also, I liked the form (appearance of the poem on the page.) I can tell you thought about many aspects of this work carefully while writing this, and the impact upon me was a surge of imagery that was both beautiful and romantic.

well! I had difficulty reading the 2nd stanza, I think a quick edit it would make flow much easier.
something like this maybe:

Ink splattered
like pouring rain
making her chilly wet
of his lines tense
in front of her iris

as you see I also changed the "you" to "her" I would throughout the poem.

 Kimchi and Karding? These people seem like they care and are being helpful.
