From a quick look at the score:
*Pizzicato is "Pizz."
*Try not to have alot of small breaks, make them a large one.
*I saw you wrote you have no modulations... I think it's necessary here.
I wonder how you can get a modulation option.
Oh wait. Did you know that one of the sites Admins is developing a notation software BY HIMSELF???
You should give it a try. I have problems with it cause I've been composing with another software for many years,
but you should use it. Talk to him about it, he's a really nice guy and he sat with me through any trouble I had with it, and gave me a full detailed explaination of how to use it that I can send you.
His username is "Chopin", talk to him about the software.
Good luck.
*This program will also let you work on a project with other people, and it'll be saved on a server so if, for example, your computer crashes while you compose it still exists.
