How can I get more attention on my art?

Im a digital artist. I've asked for brutal honest feedback on my work before and people have told me that my art is good. Like im out here begging for feedback so I can improve but people tell me my work is really good? So if my work is good, why does it get less attention and likes than others? Even if we post at the exact same time in a group, mine will get less attention, sometimes none at all.

Whats the secret
