Go back and do a better job of masking, I'm afraid:

Refine edge may help some but those type of selections are very difficult. If you are trying to replace the sky, it may not be the best method to use.

Some of the solutions I would use are:-

Next time you take a picture like that, shoot 2 pictures, 1 exposed for the foreground and 1 for the sky. You really need a tripod to do this but if you can hold the camera steady you might get away with it. Then in your IMP you can join both images together at a more convenient place rather than the sky and tree branches. Layer masks are needed to do this.

Plugins, Corrective Unfringe, Mac's Remove White, Mehdi Eraser Classic and Eraser Genuine. All are freeware downloads

In your IMP use Layer->Defringe also has settings for removing black and white mattes. Select->Modify->and you have 5 settings in there to contract or expand the selection.

A quick solution, but not the best solution, is use the lasso tool to select the ends of the trees. I grabbed the sky as well but you can take a bit more care if you want to and only grab the trees.
Go to Image>Adjustments>Selective Color and select whites from the drop down menu and then increase the black to maximum with the slider.
As I said not ideal but will get your image a little better than it is.

Most Photoshop users (and surprisingly some professionals too) tend to fall back on removing the background and then placing a new sky underneath that layer. I think it's a limited method.

I've developed a different, quick and pretty accurate technique to replace a background. The technique also works when you want to replace blue or cloudy skies. It avoids issues that are common when you use the more traditional technique.

Care to share that technique as it looks very impressive?

Here is a link to tutorial about using defringe command in PS

Another quick way would be to reduce selection by 1-2 pix
