I don't even know how to start to reply X'D I'll make sure to take the tips into consideration :3There's actually a term for the type of poetry you've written! An ekphrastic poem takes a piece (usually art, but any type of creative work counts) and tries to describe or interpret it. For your poem, you're interpreting Homestuck. William Carlos Williams' Landscape with the Fall of Icarus is one of the better examples of an ekphrastic poem.
Your use of bolded text in the poem is interesting, and it puts more emphasis on those parts. Repetition is useful in poetry for anchoring the poem to a concept or idea! (Or in your case, a rhythm.) However, too much repetition can weigh a poem down, and you may want to consider trimming down the use of the word "honk" in the piece. It's also interesting how you've spaced the poem, some lines are only a single word, while others are several sentences long. Breaking a line is important, it makes the reader take a brief mental pause. That's why your last 4 lines have more attention drawn to them. However, if lines aren't broken enough, it can read like a run-on sentence.
Your use of imagery is strong in this piece. I especially like the line "A blur of pale orange and gray and olive green." I would suggest minor edits to some of the phrasing to get rid of unnecessary words. Like for that last line, it may be a good idea to remove the words 'and' and put in commas: "A blur of pale orange, gray, olive green." That way, you still get those mental pauses, but it doesn't use unnecessary words. I like your use of alliteration as well, "blue blood, pathetically protesting". Alliteration's a really useful tool in poetry, and it can help make a poem sound more fluid (She sells seashells down by the seas shore) or more grating (Clean clams crammed in clean cans) depending on how it's used.
But I did enjoy reading the poem; I have to admit, I never thought I'd see an ekphrastic poem about Homestuck!
EDIT: Also, have you titled this piece? If not, you should consider adding one!
Is a little hard to avoid, considering the section I was basing it off has "honk" consistently in each panel- even making up the entire background in one.However, too much repetition can weigh a poem down, and you may want to consider trimming down the use of the word "honk" in the piece.
