Not nearly as beautiful as your shots, but these were taken handheld with shutter speeds from 4-8 seconds during a storm (max winds of up to 80mph), you never knew if these little bugger rockets would shoot up or sideways..... I just like the ambiance. Was my 1st week with the 5d, didn't know how to raise the iso in the dark and slight rain, was at 3200. Next time I'm sure to get out the tripod.
