Scales

Cool Shot. Very good composition. IMHO, if you position the people slightly to the left it will look even better. Just an idea, but this is already great!

You should have waited till the people were either more spread out, or just plain a lot closer to the bottom of the frame.

Great perspective and exposure. Sure, the people could be in better positions, but still a nice photo. I think it's even stronger with the suspension structure (top right) cropped out, but that's subjective!
