It seems like you need to do #selfintroduction tag post and introduce yourself. Those usually make people their first few bucks. Just say who you are and what your doing why you joined steemit. you don't have to give your identity to let us know who you are on steemit. However the more you share the more you stand to make. In my experience anyways. There is no one way to work for all people.

You are new here so it takes time to get the ball rolling. I have seen people come here and make over $15,000us for their first post, seriously. But they were popular online and had friends here already and brought more with them. Other I've seen write posts for months before they started banking rewards. Its very chaotic and there is no single formula for all.

Your art is good and once people start to know you more you will get more votes promise.

When it comes to art its really important you can prove its your art. Far too many people came here, posted others peoples art and then got busted and everyone was mad because they voted for a fake. This good for artists and their work because it help protect you as well.

So you might want to verify your identity or at least confirm it's your art.
