What is the best strategy to succeed in the Envato marketplace?

I’ve joined this online field almost one year ago. And I got a lot of information about this online field. One of my friend told me about the Envato for my digital products. Actually, I make a website templates.

Recently i created a website template for grinch costumes. So after seeing my work my friend recommended me to Envato to get even more recognition.

But i don’t know much of the Envato therefor, I am confused about how to get succeed at such a crowded marketplace.

Is there any strategy to overcome this or Some kind of tips?

Thanks!
