I am also relatively new to HubPages (I joined months ago but didn't do anything except throw in a few half hearted articles, I am back for good now and am publishing fast :)) so my advice will need to be verified. But I think your article did not pass the QAP (the new quality assessment criteria they've put into place). I am not sure if they'll even send a notification if the article doesn't qualify to be published, but in the meanwhile you can spruce up your article will photos, videos and polls etc. I think that will increase the chances of your article getting approved. Of course, the content will have to be unique, high quality and well written (I think that goes without saying).
All the best to you Rija.
