Great shot as usual...BUT raises a question to show how much of a newbie I am. I'm guessing you set the ground as your horizon and not the wing line of the plane which seems a little low on the left side. Would there be any instance you'd edit the other way? Reason I ask is my eye was immediately drawn to the plane and wing which looked off. Then I noticed the horizon and then the relationship between the two.
Just curious.

From my perspective, unless you know for a fact otherwise, the ground is always level. The things sitting on the ground, not so much. 
We could tell this IAR bird was sitting a little low to its right so I left it that way.

Gripped, 50mm f/1.8, 18-55mm f/4-5.6, 24-105mm
