I am very surprised that someone with the Harvard University English Department (search the profile image) would have such a time with English.
As for your lack of sales: As a Harvard man, you must know that your start date on Fiverr, November 2017, was not 4 months ago, but perhaps just 4 days ago. So you must give your tired logo design gig time to percolate, your uninspiring rasterizing gig time to blossom, and your logo design gig time to bring in plagiarism complaints.
Bottom line: Your gig image sells your service, if your category is graphic arts. Your images are…meh.
