One think that seems to insist its presence when i read this is the Tarot card, The  Moon, which is ruled by pisces. The moon is about the world of the wild under the the moon, the raw creation and manifestation, as well as the chaos and fear. I believe that your being double pisces makes you struggle to be true to yourself, and thus you look for answers. I think, more can be told based upon your ascendant, venus, and mars (and maybe even mercury), as these can help to determine a little more what instinctively orients you.

Specifically, though, i feel like because you are a double pisces, you are prone to feeling what cant be described normally to people, so with this alone, this would imply that you are extremely talented withe eihter art, music, writing, and occult sciences.  You are probably heavily influenced by your surroundings, being like a supersponge for the emotions of other people.

Something else to keep in mind is that early signs are different than later signs. For example Kurt Cobain is an early pisces (feb 20th birth), i am a late pisces (march 19th birth). Also to take into consideration,  Kurt Cobain has a moon in Cancer, not pisces (his cancerian feelings is in part PROBABLY what made him famous...). http://www.astrotheme.com/portraits/uhvAv6pE68yN.htm
