I would key out the blue sky, I've keyed out worst. Then I would add more trees in. That is the easiest thing to do.
If you don't want the trees I would not waist the time roto-scoping every frame / 5th frame or whatever. Motion can roto scope something this simple for you. I cover this in my
training DVD Moving with Motion. Check out my
Kinetic Typography tutorial and it has an ad at the end about how my training dvd covers that subject.
Best of luck.
