Hi there,
Add more renders from different angles.
In addition, it will be even better if you additionally make renders with a wardrobe in different interiors.
Delete all duplicate clothes and shoes this very spoils the render with its unrealism and reduces the cost of the model.
It immediately gives the impression that the model was made quickly without minimal effort, as a result, there is no desire to buy it even at such a low price.
If you fill the wardrobe with things different in color, texture, seasons, the model will become much more attractive.
Best regards
