Congratulations on venturing out in the dark for some photography! Night photography is exciting, I think!
With the photos presented here, I just cannot overcome their massive compression artefacts, though, and I wondered and wondered some more what might have brought those about?
You saved them at highest resolution, which will lead to Photobucket doing their own compression. I can't tell at which SIZE you uploaded them, they are all different sizes here, which might ALSO have been Photobucket's doing?
Then I wonder if maybe these are crops out of a much larger photo? So that in the original pics the wheel is much smaller?
And I assume you took these handheld. You chose the widest open aperture your camera can give (f2.8) and used a relatively high ISO (for a FinePix), which will have given you much noise, too, I assume (well, I assume, it's only that for my Powershot 200 ISO is "on the brink" of being too much, photos taken at 400 ISO are for the bin. All of them). And you exposed for 1/9th of a second. Which will lead to camera shake, only very few can still handhold that shutter speed.
The wide open lens explains why all light sources are bright blobs.
The slow shutter (and no tripod?) explains why there is a bit of shake to be detected.
The relatively high ISO explains why there might be noise.
Nothing, however, explains the huge amount of compression artefacts to me...
