Very relaxing, I like that the stress goes down when you rest. The pictures were so cute, and very well chosen. I loved the palette choice too. Such a genuine pleasure to play.
One thing I wanted here was a slightly pointier cursor. Especially when filling in single pixel details, it wasn't always exactly clear which pixel was under my cursor. Maybe highlighting the exact pixel you're touching would do the trick here. (Didn't affect my rating, just a constructive note:) )
