An avid reader of English-language poets such as William Carlos Williams and Stanley Kunitz, Ilchenko is one of the best Ukrainian poets writing in free verse today. His poetry is associative, flitting, and fragmentary. At times he does not form complete sentences in his poems and links words together into phrases before shifting into another thought or idea. The language of his poetry has a tendency to collapse into itself, often forcing the reader to reevaluate a word or line, to reread a previous word to focus on the poet's inner logic. This fragmentary incompleteness and permeability mimics much the way human consciousness works without the filter of the written communicative convention of sentences and grammatical structure.
