Shadows seem wrong. Shadows on the P-51 are pointing down the left wing and fuselage, but the light on the small twin parked in the lower right corner of the picture seems to be coming FROM the left, almost at a 45 degree angle relative to the picture. The shadow for the nose of the aircraft is retreating behind the aircraft itself. Shadows on the cart and people inside it also seem to suggest the sun is in the upper left side of the composition, whereas the shadows on the P-51 would have to have the sunlight coming from the upper right side.
Your so close, Krusty. Based on the shadows of the cart and red plane, the shadows place the Sun just left of directly over head - not 45 degrees but less than 10.
I added some lines from the shadows through the object projecting the shadows to indicate the light source. Each orange line is identical.
1 - Right rear corner of the cart's roof.
2 - left leading edge wing tip
3 - tip of prop spinner
4 - canopy frame intersection
5 - tip of nose on red plane.
Same light source.
