Interesting feedback. I did use a tripod by the way so there should not have been any movement. I had forgotten my shutter switch but I set the camera on a 2 sec timer so there would be no movement when i pressed the shutter button. The ferris wheel turns slowly so I used a 2 sec exposure to capture that movement. I masked in the starry sky from another image I had shot the previous day.
There's definitely camera shake. Could have been wind, unstable ground like boardwalk or platform, or a strap blowing. You should be able to get sharp shots on a tripod regardless of how long the exposure. There's no real element of composition. The negative space doesn't add to the image. Think about what would make the shot different from what anyone else could do, and then work toward that.
