I agree with Gail, the color is way too bright for a background.
Personally, I'd go a little less than the correction she has made, that is one powerful color for a background. 
Also, I'd like to just mention, it's called, "dodging", when you lighten a light area, and "burning" when you darken a dark area.
If you were dodging a dark area, it would become lighter. 
That's from the days of when it was done in the darkroom and we'd use a 'wand-like' object to keep light from being exposed too much in one area.
We'd use an opaque sheet with a small hole in it to burn areas we wanted darker.
I like the dog shot by the way, very nice job, especially with Gail's edits.
