looks p good, but imo if you're going for a realistic style the stars shouldn't be so defined [also what's going on with those line stars] and the clouds should be a little less towards the traditional 'cute little ball of fluff' shape
either that or the clouds just look a bit wrong with the underside fluffy and the top side flat instead of the other way around
i'm not sure really
I feel like the style shes going for with it is like a semi realistic, yet cute style, cause thats kinda what she does, except this one has more realisticness than what she usually does
the line stars are a little weird though yeah
