2 weeks and still not an order

[shril_lex]

Hello, over the last 2 and a half weeks, my Gig has skyrocketed to over 400 impressions with 20 clicks, and 28 views. Of course, still no order. I don’t think there’s a problem with my gig not being “unique” enough since I doubt anyone else on Fiverr is offering the same service.
Are there still any improvements or tweaks I could make?
