I like it, but some of your synths just don't sound right together. The third one you came in has too much attack time, and too much tremolo. It also mutes out the bass, but the melody is nice. The drum loop is also quite repetitive throughout the song, you made variations of the melody but didn't do much with the drums at all.
But hey, for a first, this is nice. :3
Edit: Now that I'm listening with headphones, I noticed that that reverb-y part sounds a bit out of place at times. Especially in the beginning. I think that should come in later on.
Oh and because you used those effects it's not really 8bit anymore, the reverb sounds too smooth for 8bit, unless you can show me, because it sounds blended together at times.
Also, this sounds like Megaman Battle Network music. :o
