Not complaining, just curious

[temelan]

Hello everyone !
So im on fiverr for about 5 months I think. and my most ”successful” gig was the one with T Shirt Designs, recently all the stats on it dropped and become red.
My rating is good ( except two confused buyers) and my art is good quality in most people opinions so Im wondering how does this work.
Ive changed my description, prices, samples, titles and still nothing changed. I would like to mention that I have a total of 8 gigs active for quite some time now and there is nothing happening there either, am I unlucky or not good enough ?
If anybody can share some advice or something it would be great, thank you !
