A good night time exposure and obviously a tripod was used to steady the camera. Although it is a clear photo, it does not hold the attention because the subject, which is the ferris wheel, competes with the roller coaster for attention. Perhaps a closer perspective or some creative cropping would enhance the overall quality of the image.
i really like this picture, but those stret lamps are very distracting, especially the far left one against the blue wall. maybe a different crop to take that out?... nice job though
