Why rejected my vector image?

Hello everyone!
Has been rejected by another vector image on Mardi Gras. What’s wrong with her? Please analysis :wink:

Not too keen on the colours, I don’t think they go together that well. And I think the font could be better. What category is this meant to be in… it’s a bit limited in its uses just as a flattened image, and there’s not much to it if it’s a flyer/poster?

Sorry to say that but this item doesn’t offer anything as a premium. You should consider for better design or composition

Thank you all for analysis.
