This happens to most sellers, it partially because a lot of people dislike Fab compared to the previous ue marketplace. You can see that with the free 2-week content where they got bombarded with low rating.
You can find people’s opinion on reddit, and they are all just hate against Fab(latest: https://www.reddit.com/r/unrealengine/comments/1id7wd1/i_hate_you_fab/ )
So it not entirely your fault, to me your assets look pretty good. I’ve barely sold anything in january and 0 sales since 22 January so far. I hope Fab getting better but i suggest having a plan B meanwhile because most fab team are newbie, so it gonna take a very long time before clients trust Fab.
You could try other store like Unity or proposed more formats for your 3d model.
Make sure your product has a good visibility when you search them by playing with name or tags.
