Questions

I’ve written over seven novel length stories and I’m sixteen. I’ve never tried to get them published but I put them on Fictionpress. Good reviews. Grammar is something I’m currently trying to get better at, but it’s not horrible. My tone and mood is what I get the most compliments for. Also, I tend to be VERY detailed in imagery and so on. When I write, I want people to see exactly what I see. My stories are not forced. They are more like ideas that won’t go away until I tell them. I have some weak spots, obviously. Being a writer is a dream, but I have few questions on getting a really well thought out novel put out there.
How far should I plan ahead? How much background does a character need? What is a good pace for the beginning? How can I make a subplot that won’t over throw the main plot? What is TOO much for a reader to handle? A good way to keep a character IN character?

Thank you! I just want to get better. That’s why I put so many questions. Answer what you can!
What I meant by a good pace for the beginning is what is too fast or too slow before the main plot starts to flow. Does that make sense?

What is the significance of color in poetry?

is it considered a form of imagery?

Can it relate to a speaker’s feelings? If so than in what way?

Thanks in advance

I am writing an english short story and I have decided that my main character will eventually go insane. He is in a gallery and thinks that the paintings are giving him sinister looks. Its night and he is alone - if that changes things. Any good metaphors. Don’t tell me that I should do my own homework. I am also thinking about it. Please don’t go out of your way - if you tend to have really creative ideas or something then go ahead!
