Did you apply for the AdSense account through HubPages. Then it would get rejected as AdSense needs:
a) a rich amount of text content in the webpage that you are planning to use for hosting the ads
b) considerable amount of webpage visits
I can see that you have published 2 hubs. I have heard that it takes at least 10-15 hubs to get enough text content for an AdSense approval. And with those many hubs, your audience would also have increased and traffic generation will be more.
I also got rejected by AdSense for the same reason. Now I will apply for a second time only after I have published enough hubs.
Btw, you have a very interesting profile description, it's reminds me of myself :) I also love Harry Potter and Once Upon a Time series. Welcome to HubPages!
