[Why impressions suddenly decrease?]

Whenever I update my gig,price or gallery, my gig impression always goes down. In April, i I had canceled an order because of bad buyer behaviour, since then I am not getting any order or clicks. Then I tried to add more gigs  and updated my gig gallery, after that my gig impression is continuously going down. I had updated my existing gig because I thought that maybe am not getting any click due to my bad work, so I made new 3D models and updated my gig gallery and lowered my price. But still the same thing, low impressions, 0 clicks I also updated my gig tags by copying it from other sellers .

please suggest what I could be doing wrong.
