Photoshop :: Gradient Touch Up

I am working on a photo.

1. Use the magnetic lasso to separate the people in the photo and made them a separate layer.

2. Made a new gradiant layer.

3. Added my type in another layers.

I put all the layers together. The image of the people needs to be touched (some irregular areas from the original lasso cut)up on top of the gradient; but no brushes, wands, sponges will work to give me the same gradient touch-up.

I uploaded the photo so you get a better idea of what I am trying to describe. Look at the outline of the people. I need to clean that up; but no tools are working.
