Beaver at rest

I'm not to sure about the lighting but ill give it a go since I haven't posted a composite in a while

Looks good, but if I could suggest some tweaks they would be:
1. Plane should be seen from slightly higher angle.
2. Look at the shadows in the mountain tops. The light is coming from roughly the
   2 o'clock position (top right). The light on your plane seems to be from the top left of the image.

It is fun to look at though!

Nice, but I'd have to agree with Bajan. The perspective of the plane doesn't match that of the background. The right wing should be pointing to the horizon.

Neat edit!

IMHO the plane looks too small...kinda like a R/C plane or toy.  I love the background!
