First of all, the thing with music is that it always works, as long as you like it. No matter how dissonant, weird, or the amount of counter measures you use, as long as you have a good idea about the song, it's allright. I like the ideas as songs, if played on real instruments of course

The songs are really nicely written, and they have some great ideas in them. I'd get a band together and work out these songs, and put some vocals on them. I'm pretty sure they will become awesome songs.
I know it's a difficult thing to accept, I'm a musician myself, so I know how difficult it is, but try not to be insecure about your writing. Just write and write and write... don't throw ideas away, but remember them. Maybe they fit in other ideas.
Good luck with the songs.
