Second attempt

I was back on the roof of the Forum in Groningen tonight. This time I had more succes. I captured several images from sunset until deep into the blue hour with this photo as my final result. I'm very happy with it.
Handheld, ISO 1000, 24-70 lens, through glass. Not the easiest way and above that, way out of my comfort zone.

Earlier this week I couldn't go to the rooftop because of a thunderstorm passing by.

Now it's fingers crossed if this photo will be ok enough for my first entry in the course. We'll see.
