That's fancy, and I like it. Your definitely inproving.
The first thing that hit me was the color scheme. I love the mix of white highlights, black shadows, and deep blue tint to everything in between. I l;ike the way the headlights look, very realistic, I think. The reflections on the side of the car are sharp, too, enhancing the car's sense of speed by looking as if they were created by lights streaking by at high speed. I love your new signature, too!
But, no picture is perfect, and you knew I would find something to criticize. That criticism is something that my eye can readily detect in all sorts of drawings, pictures, real life. I started learning it in art class, and improved it when I started isometric drawing in drafting class. It's called perspective, and I'm sure everyone else can see it. I'm surprised no one has said anything. Anyway, the car is not going the same direction as the blur. I order to be correct the car would have to be coming toward the viewer at a more direct or head-on angle, or the blur would have to come together at a vanishing point that would ptrobably be about a foot to the left of the picture. That you cannot do with photoshop, you can only move the vanishing point within the frame, I wish you could move it outside and I don't know why it doesn't have that feature. If you look at PB's Italian Job pic, you can see a little funnyness with the Mini heading down the stairs, too. I would say to only do the perspective/depth blur on pics where the car is coming at a straighter angle.
Other than that, the pic is very artistic and very appealing at a glance. You should keep working on this. Here's a tip: PB is working on color shift paints for his pics, you might be able to beat him to a good result.
