It's such a massive thing and as it can be seen from almost anywhere, then a series is probably the best choice. A range of angles is what you have. Those with clouds that are big and bold enough to counter the presence of the Shard appeal to me. Probably that's because I don't like the thing.
Maybe that's why I like two the best. It has the clouds. It has something of old London (including low level, horizontal lines and arches that are totally opposite to the thing. We have few humans. Nice to see them in this context. Then we have reminders of the engineering required. Best of all, the Shard doesn't look real here. It resembles an artist's rendition for the planning stages. A warning of what is coming.
No3 baffles me. what is the tower to the left? I can't see it in the other pictures. Whatever it is, it must be hidden in those shots. Looking at the big glass face of the building on the right of 2, I think that the slim tower must be behind The Shard in 1??? Possibly it is the wa lens and low angle that make the column appear to be so tall?From the sky, I think 3 must have been taken on a different day.
Re 5. Could the clouds be darkened a little to match them to 1,2 and 4? The positioning of the Shard so it thrusts up through the rent in the roofline makes a statement. As do the railings that are more or less horizontal and their pedestrian connection to the lower level buildings.
Still, The Shard is a welcome relief from London Bridge and I note how careful you were to keep it out of the shots.
