Ok here are a few tips:
Use a rhetorical question at some point - this is a language technique that is definitely found in feature articles, but not in normal newspaper articles.
Also throw in a metaphor, and a hyperbole (i.e exaggerate things a bit) Anecdotes are also good.
Use short paragraphs and present tense, except when a past event is being referred to. Include a headline - use a pun or something to make you look extra-smart
And have a catchy conclusion - usually just a sentence or two.
my english teacher says that you can practically write an essay for it, just include the things I've mentioned above at some stage throughout it, and try and add a bit of a personal style to it.
