For 1st track Id say this isnt that bad at all. I say it lacks any sort of mixing and is somewhat repetitive. I'd recommend having few notes in bass hit different tones instead of just having one same note. Also everything seems pretty mono ish. You should try some stereo widener plugins. Just keep working mate practice makes prefect :) I'd like to makes remix of this also if you can provide me with .flp in case you work in FL Studio.
