I think there be a rotation between gigs, there are those who sell really well but they can not get in touch with customers, I noticed semiprofessional ago was gone, they no longer hiềm happy with Fiverr.
You must be happy with your results. You started in August of this year and i see you have 13 reviews.
When i started last year i had 2 months in blank before i have received my first order !!
Keep calm and the orders will come.
If you permit me a suggestion… Change your profile photo and use other. We are here to sell to all the world and therefore our future clients will check our gigs in all ways. Therefore, the image is important too. As a seller i like to see the face of my clients. But as a buyer is very very important. At least a nice and funny avatar.
I like your gig of hand drawings.
