You are selling a very small variety of quite niche items at a time when sellers on Ebay are generally having a difficult time. You have low feedback numbers and limited recent selling experience.
Your titles are very brief - use all the letters available to state what your item is. For the teapot, for example, you could add the colour, for the bird model, you should say it is a bird and maybe add what sort of bird it is.
Your pictures need to be clear and uncluttered so that members using their phones don't just scroll by.
Improve your listings to get more views and possibly the odd sale.
I had 60 items listed this week and sold 3. Sales are slow; selling on Ebay is currently hard.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
