lurp.
Saw this sitting in the adverts thread. Right off the bat it sounds like things are clipping pretty hard. If you're not familiar, clipping is distortion that arises when you overdrive the signal. Clipping can be nice in the analog world but digital clipping always sounds really lame. Try compressing your sounds a little and turn some levels down.
I liked what you were playing with in terms of panning. Panning can create the illusion that sounds are louder than they really are so if you pan things up a good bit you can actually turn your levels down and have more room to mix. I noticed that some of the panning was moving from side to side. I always love the sound of that but keep in mind that some speakers can't handle that. Some people will loose a good bit of the sound if you pan like that :(
Other than that I liked what I heard. Awesome melodies, cool rhythm. Drums sounded a little iffy but not enough to really bother me. You're on your way for sure. Keep working on your sound, keep making jams and you'll be pro in no time. Practice makes purfect.
