I think that hillside is farther than it may appear. It looks to me to be at least a quarter mile beyond the plane. It's a neat shot. It is is perhaps a little too centered from a photgraphy perspective. You don't want to lose the far mountain range by cropping from the left. Why not try cropping some of the foreground so that tha plane is about 1/3 from the bottom and 2/3 from the top. The ground underneath doesn't add that much to the picture I don't think.
Is this Alaska?
