I agree with most what has been said.
The urban camouflage is actually great, since it does exactly what camouflage is supposed to do, destroy geometry and make an object unrecognizable to the human eye.
The problem is, the texture destroys your 3D model and makes your plane look two-dimensional.
Also, there is a difference between heat blurr and motion blurr. Not sure what you were trying to do. Photoshop is another tool that takes a lot of time to master. Don’t give up.
(As for the background image, there’s a thing called “fair use,” which allows anybody to use a fraction of someone’s work without having to ask for permission first. What Silvius should have done is give proper credit to the photographer.)
How about posting some wireframe shots of your plane. I'd love to see what it looks like without the texture and background? :)
