Hi, I´m fine, hope you are too. Sorry, but I have no idea about T-shirt design, so I can´t say anything to that gig really. And there are so many reasons a gig might not perform well, if you have no idea, I certainly can only guess myself, it might have dropped out of search, people are hesitant to order because of your two not 5 star reviews, your niche might be overcrowded generally, or there may be a lot of new sellers with similar gigs at the moment, and new gigs do get a boost in the ranking by Fiverr for a while, or your gig pictures are of things that aren´t in demand at this time, or the offers you send to Buyer Requests are not convincing enough, or there are just not enough people who are looking for that kind of gig, or… could be any of that or something completely different, I don´t know.
Also, March 20th isn´t really that long ago, many people don´t have orders all the time, there´s ups and downs, you can read a lot about that on the forum, as well as you can find lots of tips on the forum on how you might be able to improve your sales, market your gigs on social media etc., so please have a look at all the information there and see if you can find something you can try out.
And, of course, keep checking and replying to Buyer Requests, but all the guidance that can be given regarding Buyer Requests, has already been given, on this and on several other forum threads, you can peruse the forum search function to find more guidance for Buyer Requests and for every imaginable issue.
