I think @mfacer gave you some great feedback.
I find your paraphrasing gig to be a little confusing. I’m not sure what paraphrasing means to you (or to your buyers) but to me it just means re-wording a document (even spinning a document) and doesn’t always imply high quality writing. If I needed my writing proofed, I would buy a gig specifically for that.
If I needed work re-written, I’d buy a gig that said re-writing or spinning and I would want a mention of whether or not that would be done manually or with software. I can’t think of a reason I would buy a gig that used the word paraphrasing other than including it as a tag or keyword. That’s just me, though, so perhaps you’ve found an untapped market that I don’t know about. You have no samples showing your work so I can’t tell what you really do.
Review gigs are difficult to sell on Fiverr now. Reviews are against the Terms of Service if done on any site that disallows paid reviews (including ones like Amazon, Yelp, TripAdvisor) so buyers are getting wary of buying them. Sellers who manage to get some orders on those often find the gig eventually denied due to complaints.
Fast proofreading is a very marketable service on Fiverr. It is always difficult to get early sales, though, since no one is sure if you are good at it. You have one negative review on your “paraphrasing” gig so that will hurt you even more when buyers are considering you. You also have no samples of your proofreading skills at all. You need samples even if you have to create them by writing documents yourself with deliberate errors and then correct them. Those need to be uploaded in your gig images and PDF slots at the very least.
A slideshow used as a video might help too. You may have to really work buyer requests to get some sales, and you may need to offer deals that are highly competitive so you can prove yourself. You’ll either have to offer something very unique or worth a buyer risking $5 just in case. With great sample work and offers of super-high word counts you might get some reviews to build a reputation.
