Austenite, considering the style and scope of your music you owe it to yourself to buy the very best orchestral libraries that you can afford. Just consider this a friendly suggestion. I don't know what notation program you use and I don't know what soundfonts are ... but I use Sibelius and I would consider its built-in sounds "bad sound." Actually, some of them are OK. But anyway, it allows you to use third party "sound sets." Finale might also allow this but I don't know. And fortunately for you these excellent libraries have come way down in price, some of them by 50% from a year ago. You will be absolutely amazed at your "orchestra" after an "upgrade!"
Some subtleties in your music I missed because of the soundfonts, which was a shame because I couldn't adequately critique your music either, except to say that I liked it. Feel free to PM me if you want to move forward on this or have any technical questions.
