Road Mirage WIP - Advice?

[jacko]

Hey guys, I'm putting in a mirage on the (3D) road combined with heat waves for a TVC job. The 3D animation was submitted to me and I am using shake, and After Effects - Image Lounge's "Mirage" plugin. I think the heatwaves look nice, its just I am not happy with the mirage/reflection. And the bummer is it is very hard to find good reference material. I layered the reflection (with animated mask) over the top of the animation and then put the AE/Mirage on the top and bottom of that immediate horizon.

(I am aware of the dark line on the horizon)

I have attatched (hopefully) my current effort. I would appreciate advice on the mirage!
thanks for the help folks!
I know the file is kinda big, apologies

Looks pretty accurate. But remember, a mirage is heat waves bending light, and heat rises. Your mirage effect looks like its falling to gravity and needs to rise up. Keep working on it. It looks great.
