Yeah this sounded like one of these classes where they try to give you morals that you're supposed to know by common sense. Yes it needs work..but don't confide on people to tell to it's perfect or not. Keep writing for yourself until you realize that your work is getting better.Then people like us can appreciate your work..but still not say it's good or bad. Anyways, don't worry aobut the cliches too much..even if ppl don't say cliched words doesn't mean they don't write about cliched themes..example poetry aobut llove. I say that if you write a poem on love,make it extremely original, because many people will say "O it's nice"..but that's it..it isn't amusing. So don't worry..many writers may have written much mroe than you but they still repeat themselves..and that's what's really wrong.
"Silencio..no hay banda..no hay orquesta."
"We hear a band yet we don't see a band". It is all a recording."
"Silencio. It is all an illusion".
