WHAT DO YOU THINK OF MOST OF MY FIRST CHAPTER?????

I think your major problem right now is grammer, miss use of some word, punctuation, and sentence structure. You are doing well, I like it. Keep on writing, you are off to a good start. You can always come back and groom the piece later. Also be aware of your details not to contrdict your self. i.e. he jumped out of bed, but them he was catious not to make creaks to wake his brother. Jumping is something abrupt and quick and not very careful. But he can jump quietly or softly onto the rug by the bed or whatever....)
