That matches up -- it was indeed cloudy/overcast in Dubai on the evening of January 11th.
The pictures in general look great to me, don't get me wrong. And I don't care if ISO 6400 turns out to be a stop further than usable -- it looks like ISO 1600 on my K10D, so that's still a two-stop improvement.
