Thank you for your comments. I completely agree with them and am forwarding them to my composition teacher for his thoughts.
This does raise an interesting overall question, which I am sure has come up many times before. I wrote this piece after starting composition about six months earlier. I actually "completed" four other works prior to this but didn't consider them yet to be finished enough to consider publishing them. I expect to rework at least two of these, perhaps three, and in a couple of cases expand to chamber works and in one case a band piece. Prelude was the first piece that seemed developed enough to submit to people for comments. I actually had many of the same concerns that have been raised in this format but decided it was at the point that it made sense to see how people would react to it. In addition to this forum I posted it on several other forums and have received some similar comments from others. However, one place I posted the work for comments was the piano teachers guild in my home town of Madison, WI. Somewhat to my surprise, several of the piano teachers liked it well enough so that it looks like at least two and possibly up to four local students are now working on the piece for performance in a spring recital (I feel very honored by this and didn't expect this).
So the fundamental issue is whether to leave the piece as is and learn from the excellent comments I have received so that my future pieces are better or alternatively revise the piece in accordance with the feedback I have received to date. Since in my real life I have been a software developer for more than 45 years, I am very used to releasing new versions of software products I have created and would have no problem with releasing "Prelude in C Minor - Version 2.0". On the other hand, maybe it makes sense at this point to leave it as it is as an example of my "primitive, early works"

, especially since a few people are already working on the piece. When you look at early works from many great composers, they are usually not as good or complex as their later works but in most cases I doubt if the composers considered going back and revising those earlier pieces as they became better composers.
I am very open to revising the work, but wanted to raise this as a general issue for anyone new to composition.
Thanks,
Ed
