Nice happy tune. The kick drum in the beginning was a bit loud for my taste. I really like the synths at work here, especially the three note arpeggiated motif.
your simple happy melody could do with a harmony line here and there?
I would also vote to shoot the tamborine player. Have you tried the song without it? Maybe bring the snare up louder to replace it? It might add to the importance of the 2 and 4, make the song drive a little more.
good work!
