great shot, i just wanted to ask if you used any ND filter for the shot? the reason i'm asking this questions is that you used a very long shutter speed which is more than 6min for this shot and usually even with with lower iso and smaller aperture still can't reach more than around 60 sec for this type of shots...
No filter Ammar. It was taken just at first light which is about 40 mins prior to Sunrise. No you can't get a shot with a filter at that time as its basically still dark.
