pic looks blur, camera shake?

use a tripod, use a remote shutter, if u dun have a remote shutter then u can set a timer lo

You can use Photoshop and increase the blue channel color.
It looks quite blur.
No offense, just my 2 cents.
Since it was taken at night.
I assume that your DSLR automatically chose a slow shutter speed (your didn't post it).
Utilizing a slow shutter speed will capture the vibrations/camera shake and present it in the photo hence causing a blurred picture.

Picture is overexposed (too bright).
I assume that you're using a slow shutter speed with a high ISO.
You shouldn't use a high ISO when you're using a slow shutter speed.
Please decrease your ISO level... Just my 2 cents...

Set it to Shutter Priority.
Put it on a tripod.
Set to about 4 secs.
Select "Timer".
Select ISO of about 400 (play around and see the result).
Enjoy yourself and don't forget to post it here!
