The color of the shadow under the jet doesn't match the color of the other shadows in the scene.
The heat haze from the exhaust isn't blurry enough. Also, it wouldn't effect the house if the jet is behind the house, so the roof edge of that house shouldn't warp like it does.
Cool Cool I agree I still need to figure out how to make the haze not affect the house on the left.... THX for the feedback
Oh and about the shadow of the plane, I tried to match the color of the shadow the plane to the color of the shadows of the live action footage but could not get it right, any way you could recommend i do that....?
