Post the brief, please.
I like the overall appeal!
I would make the 2 cotton candy much bigger that is the focal point of the graphic
since cotton candy is fluffy, try using less clouds outline and maybe ad more contour on the pink by using lighter and darker hues to bring out the cotton candy.
I hope this helps!
I’m with @HotButton, I think we need a lot more information to offer a meaningful critique.
