That's a brilliant shot, can I ask where it was taken from?
Cool, I really like it. Possibly you have gone just a few minutes past the sweet spot of the blue hour, and I would clone out the lights (planes?) in the sky near the shard but great stitch.
Thanks!
Actually those two light spots next to the shard are planets! One is Jupiter the other is Venus I think, they were there for a few days and slowly moved across the sky and out of alignment
