Holy crap, these are pretty catchy! I really like
this one and
this one, they're the ones that stand out the most.
Really, you've got some good things going here! But I do have to ask: did you use a DAW(music software)? If so, then I suggest you play with the note velocities and pitch-shifts, and whatnot. The two standout tracks sound fine, but the others sound pretty same-ey, especially the last two (at the very bottom). Play with the timbre, it'll make your instruments sound more like they're being played by humans.
Also, play with your time signatures more. This isn't criticism, but more as a general suggestion. I like the latest track because it's different; both in tone and rhythm. But take this statement for granted because odd time signatures =/= good music.
Overall, you've got talent! You know the basics, you know how to make an intro hook. You just need to experiment more so that each track you make doesn't sound too similar to the others(unless that's your goal, which is okay, but it doesn't mean they have to be almost identical).
I followed! Can't wait to hear more if this is what you're offering.
