Hey there, and welcome to Fiverr!
Regarding your post: considering that you don’t have any reviews on that gig, the pricing might put off buyers and make them run to someone cheaper or at least to someone who has more reviews - I think it would be a good idea to try starting lower on the pricing until you obtain some testimonials that prove your gig’s value and results, and then incrementally up the prices.
Getting reviews naturally can only be done if your gig gets purchased and you provide a great / memorable experience to your customers - great experiences & results are what drive buyers to leave reviews 
Also, if you get buyers to purchase your gig, don’t be alarmed if not all of them leave reviews: some don’t know, or don’t think it’s important, or maybe they think the gig is not matching their expectations.
