Just looking at your gig I would recommend a few things.
First of all, your pictures look awesome, and I’m sure they take alot of work.
But you might want to start off offering a $5 service at first.
This can help you get some initial feedback, and get the ball rolling.
Also, you might want to break up your gig descriptions a little bit so they are more readable. Break it into easy to read sentences or paragraphs.
Fiverr offers the use of bold, italics, and highlighting. Take advantage of that!
When your first starting out can be the hardest. But you look very talented, and I think if you do some promotion to your gig via your social channels, and offer a $5 service to start with could help you greatly to get the ball rolling.
Also, in your profile you mention that you do logos, business cards, book illustrations, collages, etc.
Why not create a gig for each of those since they are all different?
