Nice compo, a bit below your usual standards... but way above mine ;D
The shadow looks good but if it's nearly under the plane the sun must be directly above, and so the wings would be more or less horizontal i.e. in line with the frame and they would look short and fat, and the body of the plane fat too - your shadow as depicted would only look like that if the sun was more or less in the same plane (

) as the wings off to the right of the pic, and in that case the shadow would be 'out of shot' to the left. Or am I mistaken :-?
