How to improve sales?

Hello! My name is Valeriia. On this site I presented my models. But more than half a year they are not for sale. Maybe I’m doing something wrong. Please, look at my work. https://ru.3dexport.com/valeriia
I will be grateful to everyone who will visit my portfolio, will give me good advice on how to improve sales!

I know ways to help you make sales. Send me an email to discuss further: yakecen@hotmail.com

There are several factors that might affect sales, such as marketing, economy, and the product/service itself. So, you better share a bit more details

oops...she probably didn't find the ways to improve her sales. You know, that's sad because her models are pretty good and I'd like to get them. Unfortunately, many sellers give up very fast because they don't know how to get new customers and provide better services. And of course, the majority of the sellers don't have their organizational or management teams. They're trying to do everything and eventually fail. They don't know how to work with sales signals or salesforce software, or even with ads. I suppose many sellers gave up because they have a lack of skills in marketing.
