Looks really cool! but... looks like you allready have dust on your sensor =/

How high was the ISO?
And how small was your aperture? Looks nicely small.
And maybe you want to clone out the dust, else you will always be reminded of the fact that you have dust on your sensor (I have the same and clone and clone and clone ... like I was saying earlier, I don't dare to go about cleaning it by myself).

Forgive the newbness, how can you tell there is dust on the sensor?

Dark specs in the top right of the image. It's either on the sensor or the lense.

Do you mean high ISO or long shutter speed?

Because you would have been using a tripod or other support...there is really no reason to use a high ISO setting.

There are several dust spots...they are usually more evident when shooting with small apertures and in an area like blue sky.

OOPS,I ment low ISO,I set it at 100 but I had no tripod.I was on an island in the middle of the road and set the cam on a...thing that is there so that drivers see the island and dont drive into it.How do you clone out the dust please?thanks.

You open your pic up in Photoshop (do you have Adobe Photoshop?), then use the clone tool which is among all the tools you find on the left (the icon is a STAMP), chose a part of sky that is clean, press ALT (the stamp will show), then release ALT and go back to the ring that had also shown previously and move that over the spot (you can also vary that "ring" in size). Above, next to the stamp that shows you are in "cloning mode" will also show a "brush" sign ... that is where you can vary the brush in size.
