Help needed with debut novel

I am currently working on my debut novel and I am just down to the editing stage which is proving difficult. Since there are a lot of great writers on here I wanted to know if there would be anyone willing to look over a few chapters for me, they are quite short, and just point out which bits they like, don't like, or don't need to be there, bits of plot which need improving. I'd value the opinions and anything constructive.
