"Well, I have PMed Thomas to see if it would be alright for composers to omit, if desirable, percussion and piano, and possibly the saxophones."
I can work around the percussion and saxes, I'm just awful at keyboard notation.
"But, you should really try to learn to write for piano!

It might be useful, down the proverbial road, like if a famous pianist tries to comission a concerto from you, and you have to say no because you always shyed away from writing for piano!

"
I can't imagine a known pianist would ever comission a piano piece from me KNOWING that I have trouble writing for the piano.
"P.S. You seem to view your compositional problems as things that can be stepped around, or hidden, which is usually not really conducive to bettering your compositional skills. I say if you have trouble writing for a particular instrument, write only for that instrument for a period of time, to widen your knowledge by application. Just a suggestion, of course."
I will be taking advanced theory classes in composition and orchestral arranging soon, and I'll be able to hash out many of my problems at that point. However, I will not have figured out my technique in keyboard writing for quite sometime, and I really don't want to experiment with it on a competition I intend to win. I won't make a fool of myself by turning in anything that isn't my best work.
