My Fiverr earnings fell down to 0.

I've registered on Fiverr 1 year ago. I was not working anything serious until August 2013. In August I've created a few gigs which brought me 470$. But everything was perfect until November. Since then I have no orders. I've been waiting until January 1th. Since I had no orders I decided to remove my gigs and create new ones. But it did not help. 22 days now and still no orders. I removed those gigs too and I created a new gig.

This is the gig. It seems pretty well done to me. I am very disappointed and that's why I contacted you there. To see if anyone has the same problem like mine. Thank you

all best
