Love the melody and chords man! Sounds great =)

Not bad for a first try. I don't profess to be an expert on these matters, but IMHO, there's not enough buildup and release in some parts. Adding in a few "transitional" beats (such as rapid snares fading in or something) might be worthwhile. The breakdown sounded kind of rough. The opening synth is also a bit loud and domineering compared to the rest of the composition. Otherwise, it's pretty decent, and I encourage you to keep up the good work.
