Lets see..
1: The angle of the shadows on the AC doesn´t match the position of the shadow on the ground.. (See under elevator)
2: The shadow on the ground needs more dithering. With such an overcast day (or at least a not so bright one), the shadow should have less a harsh edge, even less than this
3: The focal depth is the same for the background as for the hurricane in the foreground, there isn´t any depth of field, knocking perspective out of whack
4: There isn´t any radiosity from the grass on the light underside of the aircraft.
5: The tail wheel needs to sink deeper into the grass. Its a small wheel with a relatively high amount of pressure on it. It seems like the hurricane is leaning forward.
6: The light in the background seems to be coming from the far side of the aircraft, from more or less dead centre top of the picture. Evidence of this is the small bush in the background next to the cockpit glazing. The light on the plane comes from left top.
7: the top surfaces need a bit more of a glare to them
8: The plane seems too small.
Other than that: Beautiful build!
