Yesterday I got my first review (5 stars) after doing Fiverr for like 4 days constantly advertising my gig. And because of that I got 2 orders today at school. It shocked me how quick I got them. I would recommend a bunch of people to order a gig without ratings because it feels like the most happiest thing ever to them.
Looks like you are off to a good start.
Keep telling people about your gig!
