Oh -- one more thing.
I think I would have gone for a portrait orientation, pulled back so you had the same field of view and framing at the bottom, but a bunch of black sky above the rocket. There might also be some interesting compositional opportunities with an off-center framing, perhaps with just the towers to the right. It'd also be neat to get a bit more elevation for yourself for the shot, to be able to include the launch pad in the shot rather than have it be obscured by that building. Indeed, if not too unsafe, the roof of that building would be the perfect spot....
Here's hoping you have lots and lots of opportunities to experiment with this...sure wish I did....
Cheers,
