First, excellent work it looks great.

The grain areas that are lighter are due to a tighter grain and higher resin content baring the stain from pentrating.

You would probably be better off getting a stain pen or even a brown Sharpie and going over the areas that are most bothersome to you.

I am not really sure a stain pain will do any better of a job then regular stain. A brown Sharpie will ay the brown ink ontop of the grain.

From the one picture I don't know I would do anything.
