Well there is not much you can do if you already updated the gig image, title etc..
Just be patient and active, maybe send a few buyer requests.. 🙂
Maybe if you have some projects outside of Fiverr, try bringing the clients to work through Fiverr.. This at least helped me to gain a few reviews which are crucial especially when you just starting..
With all that said, even the high level sellers have 'dry seasons' so I would suggest you set up some more income streams if you're serious about freelancing.. 🙂
