I listen to most of them, and they're all kinda "meh".
All the songs seem to use the same square/saw lead, a sine bass, and maybe one other synth. There's not much variation or dynamics in or between your pieces, so they tend to get boring.
It sounds like you're using the fl default drums for some of your earlier works, though you experiment a little in other songs. (Though not necessarily for the better...)
For some general tips I guess, eq everything so it sits comfortably in its own range. It doesn't have to be drastic, just enough so everything stands out. Add some dynamics; the same melody played by the same instrument over and over gets boring, so add something to spice it up. (buildups, counter-melodies, interesting pads, key shifts, panning, bandpass sweeps, idk just something to break the monotony.) Also, going along with the monotony thing, add more than just one or two synths doing the same thing - add background elements, harmonies, an extra sound here or there - make it interesting to listen to. It shouldn't be completely predictable, for the most part.
Also, wtf?
