Night clouds over Porto

The week I spend in Portugal this year, was just crazy hot (45 degrees Celsius). And with that weather, the sky was usually mostly just completely clear. So my luck for a nice sunset was just not there. But the last evening there, at least some clouds showed up in the evening, so there are some in this night shot.

This is a 2 shot vertorama, each shot from 5 exposure. First combined with PTgui, then Photoengine, finished in Photoshop.
