I LOVE the art (OBVIOUSLY)! Not much else to say besides super relaxing! A suggestion (had you had more time) was maybe a little animation in the grass and water would add to the pleasing atmosphere. 

Adding on to that, maybe a particle effect starting from the top right that just rained (very few) petals. (More relaxing polish)

WOOOOOOOOOO A+++++++++++++++++++
Awesome art and gameplay
