Beginner trying new things, need advice on what's missing in my poster

The objective is mostly just trying to give people an encouraging sentence as beautiful as possible.


the audience is social media users.


so I decided to go with a flower image and I added pointillism and some kind of blend with colors to achieve the look. I also tried to go as minimalist as possible.


so my general issue is, I don't know what's missing here. it feels empty in a kind of way I can't explain nor fill.

Any help is appreciated, thank you!
