>DYNAMICS and PHRASING
Um, what? Sorry, I'm new to the composing thing, so I'm not entirely sure what you're trying to say. Do I need to add dynamics and clarify the phrasing?
>it's not all that ideomatically written
Can you elaborate? What would be idiomatic and what in particular makes this one not so? I'm confident that it's not idiomatically written as I was just making a good sound rather than following any rules or styles (because I don't know any). ;)
>theres nothing really unique to the instruments being done
Meaning, it doesn't cater to the strengths and weaknesses of the instrument?
>it also looks as if it were written by a pianist
I wish I were a pianist, then I'd probably have an easier time with theory. The only instrument I play is the flute.
>only that it is very diatonic, short and therefore predictable
I seem to be all questions today. Can you specify what you mean by "very diatonic"? I would expect that with nothing but the key of C major, but I'm not entirely sure how that makes it predictable.
Thanks for the comments, by the way.
