nice start!
Your off to a great start! you still need to make your song more coherent and a little less cowbell. unless you like the cowbell. before i go further i want to ask if the song is still a midi and if you intend to make this into an mp3?
basically the sounds dont play off eachother. you have a strong synth a blippy base and a bouncy cowbell. the notes to the song are fine but i bet if you stuck to a more centered focus of sound this track can be made into a great composition.
if it is still a midi I could remix it into an MP3 that demonstrates what i am talking about for you.
good luck!
