I did up to 5.
Look, the way I see it there are 2 ways of approaching composition (this is in my amateur opinion)
1) You think about what you are going to write, the cadential points, the styles you are looking for, the modes you are changing, the interesting modulations etc. etc. you are going to do and you write a well thought out piece which is technically advanced and theoretically based.
OR
2) You write the thing then analyse it later.
I went with the former option, because for me, music, in its essence, its about the sound. Therefore, if it sounds good, there should be no reason why it isn't good. Furthermore, what is "good" is highly subjective.
I wouldn't worry too much Estel. Write first, worry later. Look for things to justify anything you need into your work afterwards. If you can't find enough of whatever you are looking for, add it!
Its your composition, your baby. Enjoy!
