Long exposure - dusk & dawn

Brief

I love long exposure photography and the mood it can bring. Here I would like to see your long exposure shot, taken with a shutter speed of at least 4 seconds. Images should be taken at dusk or dawn, that is to say after sunset or before sunrise, no sun should show in the pictures. You can photograph any topic/subject. Obviously for long exposure shots, moving elements (water, clouds ...) always add up to the effect. Looking forward to seeing your masterpieces!
