I like the texture of it. I think the color is just a tiny bit too blue, and maybe just a little too saturated. Before you start changing the color, though, try stepping through all of the blending modes and/or adjusting the opacity of the trees layer. Just pulling some color from underneath might be all you need to get it to integrate really well.

Whichever way you go, though, I'll bet that the change you need is very small—it looks almost right, but just a little bit off.
