Splendid piece of work!
EDIT: Just corrected grammar
The animation was properly looped, and the little things were appearing sometimes normally, sometimes very delicately, felt like you were walking down a magic road buried in interesting scenery/thoughts, only to suddenly stop and look around, to be surrounded by a magical garden. I really liked the snail, not sure I normally see anyone going to lengths to properly show someone how long does a piece takes place :)
The animator did a great work syncing all of the effects to the music, showing that he indeed, is inspired by it, and no wonder!
The music itself is beautiful, worthy an animation, game, a movie, a theater play. I'd love to come and listen, but I'd had to hide in the crowd so that no one sees me crying ^_T.
Overally the work of Art here touches oneself as me. Especially the last part with the "pollinating scene" after which everybody started vanishing. It felt like you wanted to symbolize a passing of time and people, but not a sad one - a joyous one, promising new Spring to come.
Well done~!
