Various incomplete compositions

Instead of creating a new topic every time I start a composition and want suggestions or feedback on it, I will use this as my sole thread for uploading various past and future works-in-progress.

The first two were started half a decade ago when I first got a piano and started learning to compose music (107 is pretty rough just before the middle point; it needs revision there). The second one was started yesterday and, I hope, works well on a harmonic level. It was a test for a certain technique that I invented, a technique that I hope will provide a strong foundation for writing chord progressions.

42's main issue is that your melody and harmony don't seem to agree with each other. The main instance of this was in the beginning where your progression resolves to i but your melody still outlines the dominant. 
107 starts out with a pretty cool idea, actually. I like it a lot, I just think it could use more instruments and a better soundfont, but I like where it is very much.
D sounds like it's trying to follow a Baroque chain of suspensions but doesn't follow the proper formula of preparation, suspension, resolution, where the resolution is the preparation for the next suspension. Just follow the formula and it'll work, even in canon.

Yes, D is definitely liberal in its treatment of dissonance. The difficulty I had was that getting the voices to move into the desired harmonies required a lot of leaps into dissonances. I didn't want to sacrifice the integrity of the progression to considerations of dissonance treatment. Perhaps I should go back and insert some chords in between the chords that are already there so as to make the flow a bit smoother.

Here's one I started earlier tonight.

Another one. Actually, it might be done, but it's too short to have its own topic.

This one is a short canon.

I started another canon today. The voice leading proved to be difficult, and it steered me into a high register. I wonder if I ended up going too high.

I finished today's canon. There are one or two spots that bother me, but I'm not going to try changing them.
