This is so lovly! Yes, the colors and composition are great and the kid shows an intuitive sense of it, but the feels and the childish optimistic view are what makes it great.

This makes me happy looking at it

As an art critic (seriously, I get paid for it… sometimes), I’d like to tell your 9-year old that their work is superb. The use of colour and spacial arrangement is particularly deft.

I look forward to following their, hopefully, long career in the arts.
