Sweet!
You've got some nice melodies here bro! I do have some advice, and that's that you could really work on the mix here. The bassdrum is fairly weak at some points, you could help that by EQing it and boosting the lower and higher frequencies a bit. I liked your 8-bit lead, it sounded nice and catchy!
You could also EQ that crash cymbal, and put some reverb on it, sometimes it sounds way too dry and it could blend in much more then it does now.
Then for the melodies, they're really catchy, but at some points you could've made it catchier, it seems a bit like you're placing the notes sort of 'randomly' on the scale. I know it's not randomly of course, rhythmically it's great, but sometimes the notes don't go along the lines of the chords, try using notes that are in the chords at the heavier accents, if you know what I mean.
For example, the notes you place on every beat will be the chord notes, and inbetween you could use others (and chord notes too of course). It's a bit of a shitty explanation, but I hope you understand :P
Anyway, I really like your instrumentation and structure, the pads are great, your use of percussion is nice, and your melodies, even if I criticised them, are damn catchy!
Great work man, keep it up!
