Sounds good, but too mellow.
It has a kind of upbeat, cheery feeling. I like some of the effects, but I feel that your song could use many more dynamics, including a stronger bass, building drums (not background).
Mellowing out the song has a nice effect, but it seems to take away from the climaxes of the song, and probably should be used sparingly, not throughout an entire song.
However, your song does sound good, I personally like the mellow beat (a bit repetitive), as well as the choppy (in a good way) intro. Good job. :D
