This is a hard photograph to critique. For what it is, it is a technically fine photograph. The colors in the sky are really nice, and you have captured the light trails from the passing cars well.

However, there is not much to engage the viewer here. The tall street lights and the placement in the frame compete with the light trails for our attention. My first reaction was to question what the focus or subject of the image was. The light trails, the lights, or the sky? All three individual elements hold interest.

I think a different perspective and angle may have helped with that confusion. If the street lights were an important part of the frame, I would have positioned myself closer and used a slight upward angle so the lights towered above everything else. If the light trails from the vehicles was the focus I would have tried to frame them tighter. Perhaps using a landscape orientation.

I totally agree with uncommondepth's suggestion of a landscape orientation. For one, it would capture more of the light trails which I guess are the main element in a long exposure.

I also agree that there are three elements that hold interest here. But I don't think that is a bad thing. Perhaps just a personal thing but I like busy scenes.

I love the extreme sense of motion in this image. I don't think it's too distracting, but rather a nice contrast between the light trails from the cars and the darkening sky.

there's no any 'center' to be concentrated

ahhhh the colors! i'm a sucker for car lasers, tree silhouettes, repitition, and pink skies, which is pretty much what this photo is all about. it's great.
