I don't think you should do a poem or an artwork... Wasteland is a poem (you don't want to repeat text types) and an artwork is quite a restrictive choice?? You could pick it, but it would be quite unexpected and I don't think teachers would really know how to mark it.
Since wasteland (i think?) focuses on the despair of a world after world war one, I'd maybe pick a novel or film that was inspired by war, or McCarthy's The Road seems like a pretty good pick based on depressing tone.
Hope this helps a bit --> although you should definitely choose your text to fit your question
