A illustration logo for a cannabis brand

I created an image using AI to visually show colours characters positioning and logo name, however it looks totally AI and although I want it all cartoon it looks super fake and unrealistic. I need it completely improved changed and made to look business worthy and not AI generated. I really need it done by today as I need to send it off to have stickers clothing smoking accessories and organise for someone to come paint in the social club. I know this is a short time scale I paid somebody and waited 3 weeks for delivery and it is absolutely dreadful, they have literally used AI and tried to make the image better it looks terrible and can’t compete against other people logo in the community. Please get back to me as soon as possible! I’m excited to get to work together
