We like it! Especially the happy upside-down kid. The card makes us smile to see it. :) We like the meaning of the card as well.
Critiques on the art- Something seems slightly off about the neck/shoulders area of the not-upside-down kid, like the shoulders aren't connected entirely right. Also wondering a bit about the sun in the background- I like that it's more stylized, kind of a cool effect, reminds me a bit of a kid's drawing. But at the same time seems a bit too clean to be a kid's drawing, but a bit too... not-quite-clean-enough(?) (gah, what are words... like how the circle for the sun is not 100% round) to seem more like a symbol or stylized thing (gah, words failing again here. XP Hopefully at least some of this is coming across). Maybe push it in one direction or another, either cleaner and less wobbly, or more like a kid's drawing? Use a different brush/texture for the lines? Because as of now a bit hard to tell what you were going for, like if it was meant to be wobbly or not or just done quickly.
