No one sell in two month!

1). The best way to increase sales is to promote them on social media.
2). You can also provide some free models so that buyers will get a clear picture of your work and quality
3). Provide reasonable prices
4). Have patience there are many 3D artists here, so there is a big competition.

Such is what freelancers pass through.
Keep making more models and watch the market too. I too have this issue, I'm trying to put out as many models as possible

I keep pointing to this video because there is valuable info there that can help you get better sales, also explains the analytics tool in detail so you get to know what you better make and also what not to make (https://www.youtube.com/watch?v=xI_HpXuPWms)
