Working off Bob-the-Rabbid's suggestion:

Some textures would be nice.

I also think it would be funny if one of the music pieces you could choose was death metal or something NOT relaxing... Maybe as an easter egg... Just a thought.

Relaxing, but a bit boring. Of course, that could just be me and my small attention spa- HEY, LOOK! SOMETHING SHINY!

Yup, its just my attention span. I feel like this put me to sleep. Usually this would be a bad thing, but in this case: mission accomplished. It needs a bit more work.

Also, you may want to think of getting rid of that cartoony sun. The sun doesn't actually look like that. All of this is your call, of course...

You Have Something Here.

It was pretty okay. The animation was a bit dry, but here's some suggestions for a possible sequel.:

Give viewer a choice of which background to have
Give viewer a choice to select a song (with the song's name included)

Nice job, and hope to see more of you.

Very soothing...

Try to do more of this with other artists so that your work can be noticed for what it really is. I'd like to see this as a background mixed with the excellent song and more lively animations available. Overall great work.

V nice

Really good the clip fits the music, Sure the actual animation could have been better but not bad for a quick boredom piece of work, 8/10 4/5
