A short poem may be a stylistic choice or it may be that you have said what you intended to say in a more concise way. Either way, they differ stylistically from a long poem in that there tends to be more care in word choice. Since there are fewer words people tend to spend more time on choosing a word that fits the subject to perfection. Because of this meticulous attitude, writing a short poem is often more tedious than writing a long poem.
