Not download material, it really needs to be much longer and and have a few more variations in sounds. It needs a different drum loop because it just doesn't suit it at all, It also should have no drums at some points to bring out it's ambience. Your key placement with the wave sound was off a bit at times with your main melody and the stopping of the main melodies playing, sounds like my computer is skipping your track. You just need practice or just definitely need to revise it.
1. Make it longer, any song with balls is at least 3:00
2. Vary this piece with more sounds
3. Use different drums and sometimes none
4 Take out some of the skipping of the main melody
5. Fix some of the key placement with your wave/ambient sound
