first one sounds.... not good.
you use way too much reverb, the drum pattern is sloppy, and the melody is chaotic and has no real pattern. the wobble bass is used over and over with the same pattern. all in all, you used presets which i find lazy, and it is so repetitive.
second sounds better, still a lot of reverb, different synths are louder and some are quieter, it's too chaotic. the basses are not very good, a lot of it is grainy and low quality.
the intro to the 3rd was pretty cool, the drop sucked, the bass is the same generic one used by so many people, you need a more unique style.
overall, you use way too much reverb, generic basses, repetitive patterns and chaotic melodies that don't exactly make any sense.
for using fl for 3 years, you aren't that great. i'm sorry :I
