I like #3.

For me...#1 is too familiar looking and #2 is too much about the gorilla. #3 is the kids outdoors in a field.

I understand wanting the strong contrast in the sky and name but I think that the black is harsh and I would introduce green to those areas until they took on a little bit of hue. Still dark but, but not hard black.

That's my opinion. Like my wife does, feel free to ignore it. wink
