Love the perspective on that one-- it's awesome.
First and third shots reminds me of chili peppers or something-- yet it's fireworks!

But man, it's a unique perspective.
I'm behind in posting some other photos, but the ones I just took are more interesting anyway. Got there 45 minutes early for my appointed bus time, all the good spots were taken. My streak photo (first time) was total fail.

Next time, need to get there more like 2 hours early, at least for a popular launch like SpaceX Falcon Heavy.
Also trying to use two cameras at once-- one for streak shots, and one supertelephoto, was too much. Next time focusing on just using one camera is the way to go. I can maybe imagine developing the skill, coordination, and organization to use two cameras, but given I don't live anywhere close to rocket launches, it might be a bit painful to develop in a timely manner.
Also for some reason 500px's hotlink/embed previews have gotten really bad on quality. Please click for higher quality images.
